Bitcoin ATMs are popping up all over the US. They make buying Bitcoin for cash easy, convenient, & safe. Check out our website coinATMmap.com to find the nearest location. You can even get the address texted to you directly from our site.
You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments. It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
Accountable - The public ledger is transparent, all transactions are seen by everyone.
Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works. You can even run a node on a Raspberry Pi.
Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
Low fee scaling - On chain transaction fees depend on network demand and how much priority you wish to assign to the transaction. Most wallets calculate on chain fees automatically but you can view current fees here and mempool activity here. On chain fees may rise occasionally due to network demand, however instant micropayments that do not require confirmations are happening via the Lightning Network, a second layer scaling solution currently rolling out on the Bitcoin mainnet.
Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply memorizing a string of words for wallet recovery (while cool this method is generally not recommended due to potential for insecure key generation by inexperienced users. Hardware wallets are the preferred method for new users due to ease of use and additional security).
Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage. Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, then you will need to create your own wallet and keep it secure. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor, Ledger or ColdCard is recommended. Alternatively there are many software wallet options to choose from here depending on your use case.
If you prefer to let third party "Bitcoin banks" manage your coins, try Gemini but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email! 2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".
Where can I spend bitcoins?
Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out. If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.
Just like any other form of money, you can also earn bitcoins by being paid to do a job.
You can also earn bitcoins by participating as a market maker on JoinMarket by allowing users to perform CoinJoin transactions with your bitcoins for a small fee (requires you to already have some bitcoins.
The following is a short list of ongoing projects that might be worth taking a look at if you are interested in current development in the bitcoin space.
One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
one bitcoin is equal to 100 million satoshis
1,000 per bitcoin
used as default unit in recent Electrum wallet releases
1,000,000 per bitcoin
colloquial "slang" term for microbitcoin (μBTC)
100,000,000 per bitcoin
smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Disclaimer: This is sort of my own arbitrary editing, so there could be some misunderstandings. I root for the spread of good spirits and transparency of IF. 📷 Hans Moog [IF]어제 오후 2:45 So why don't we just copy Avalanche? Well that's pretty simple ... 📷 Hans Moog [IF]어제 오후 2:47 1. It doesn't scale very well with the amount of nodes in the network that have no say in the consensus process but are merely consensus consuming nodes(i.e. sensors, edge devices and so on). If you assume that the network will never have more than a few thousand nodes then thats fine butif you want to build a DLT that can cope with millions of devices then it wont work because of the message complexity. 2. If somebody starts spamming conflicts, then the whole network will stop to confirm any transactions and will grind to a halt until the conflict spamming stops.Avalanche thinks that this is not a huge problem because an attacker would have to spend fees for spamming conflicts which means that he couldn't do this forever and would at some point run out of funds. IOTA tries to build a feeless protocol and a consensus that stops to function if somebody spams conflicts is really not an option for us. 3. If a medium sized validator goes offline due to whatever reason, then the whole network will again stop to confirm any transactionsbecause whenever a query for a nodes opinion can not be answered they reset the counter for consecutive successful voting rounds which will prevent confirmations. Since nodes need to open some ports to be available for queries it is super easy to DDOS validators and again bring the network confirmations to 0. 📷 Hans Moog [IF]어제 오후 3:05 4. Avalanche still processes transactions in "chunks/blocks"by only applying them after they have gone through some consensus process (gathered enough successfull voting rounds),which means that the nodes will waste a significant amount of time where they "wait" for the next chunk to be finished before the transactions are applied to the ledger state. IOTA tries to streamline this process by decoupling consensus and the booking of transactions by using the "parallel reality based ledger state" which means that nodes in IOTA will never waste any time "waiting" for decisions to be made. This will give us much higher throughput numbers. 📷 Hans Moog [IF]어제 오후 3:11 5. Avalanche has some really severe game theoretic problems where nodes are incentivized to attach their transactions to the already decided parts of the DAG because then things like conflict spam won't affect these transactions as badly as the transactions issued by honest nodes.If however every node would follow this "better and selfish" tip selection mechanism then the network will stop to work at all. Overall the "being able to stop consensus" might not be too bad since you can't really do anything really bad (i.e. double spend) which is why we might not see these kind of attacks in the immediate future but just wait until a few DeFi apps are running on their platform where smart contracts are actually relying on more or less real time execution of the contracts. Then there might be some actual financial gains to be made if the contract halts and we might see alot of these things appear (including selfish tip selection). Avalanche is barely a top 100 project and nobody attacks these kind of low value networks unless there is something to be gained from such an attack. Saying that the fact that its live on mainnet and hasn't been attacked in 3 weeks is a proof for its security is completely wrong. Especially considering that 95% of all stake are controlled by avalanche itself If you control > 50% of the voting power then you essentially control the whole network and attacks can mostly be ignored I guess there is a reason for avalanche only selling 10% of the token supply to the public because then some of the named problems are less likely to appear 📷 Navin Ramachandran [IF]어제 오후 3:21 I have to say that wtf's suggestion is pretty condescending to all our researchers. It seems heavy on the troll aspect to suggest that we should ditch all our work because iota is only good at industrial adoption. Does wtf actually expect a response to this? Or is this grand standing? 📷 Hans Moog [IF]어제 오후 3:22 The whole argument of "why don't you just use X instead of trying to build a better version" is also a completely idiotic argument. Why did ETH write their own protocol if Bitcoin was already around? Well because they saw problems in Bitcoins approach and tried to improve it. 📷 Hans Moog [IF]어제 오후 3:27 u/NavinRamachandran [IF] Its like most of his arguments ... remember when he said we should implement colored coins in 2nd layer smart contracts instead of the base layer because they would be more expressive (i.e. turing complete) completely discarding that 2nd layer smart contracts only really work if you have a consensus on data and therefore state for which you need the "traceability" of funds to create these kind of mini blockchains in the tangle? Colored coins "enable" smart contracts and it wouldnt work the other way round - unless you have a platform that works exactly like ETH where all the nodes validate a single shared execution platform of the smart contracts which is not really scalable and is exactly what we are trying to solve with our approach. 📷 Navin Ramachandran [IF]어제 오후 3:28 Always easier to criticise than build something yourself. But yet he keeps posting these inflammatory posts. At this point is there any doubt if he is making these comments constructively? 📷 Hans Moog [IF]어제 오후 3:43 If he at least would try to understand IOTAs vision ... then maybe he wouldn't have to ask things like "Why don't you just copy a tech that only works with fees" 📷 Hans Moog [IF]어제 오후 4:35 u/Shaar
I thought this would only be used to 'override' finality, eg if there were network splits. But not in normal consensus
That is not correct. Every single transaction gets booked on arrival using the parallel reality based ledger state. If there are conflicts then we create a "branch" (container in the ledger state) that represents the perception that this particular double spend would be accepted by consensus. After consensus is reached, the container is simply marked as "accepted" and all transactions that are associated with this branch are immediately confirmed as well. This allows us to make the node use all of its computing ressources 24/7 without having to wait for any kind of decision to be made and allows us to scale the throughput to its physical limits. That's the whole idea of the "parallel reality based ledger state" instead of designing a data structure that models the ledger state "after consensus" like everybody else is doing it is tailored to model the ledger state "before consensus" and then you just flip a flag to persist your decision. The "resync mechanism" also uses the branches to measure the amount of approval a certain perception of the ledger state receives. So if my own opinion is not in line with what the rest of the network has accepted (i.e. because I was eclipsed or because there was a network split), then I can use the weight of these branches to detect this "being out of sync" and can do another larger query to re-evaluate my decision.(수정됨)
Also what happens in IOTA if DRNG notes would fall out, does the network continue if no new RNGs appear for a while? Or will new nodes be added sufficiently fast to the DRNG committee that no one notices?
Its a comittee and not just a single DRNG provider. If a few nodes fail then it will still produce random numbers. And even if the whole comittee fails there are fallback RNG's that would be used instead 📷 Hans Moog [IF]어제 오후 4:58 And multiverse doesn't use FPC but only the weight of these branches in the same way as blockchain uses the longest chain wins consensus to choose between conflicts. So nodes simply attach their transactions to the transactions that they have seen first and if there are conflicts then you simply monitor which version received more approval and adjust your opinion accordingly. 📷 Hans Moog [IF]어제 오후 5:07 We started integrating some of the non-controversial concepts (like the approval reset switch) into FPC and are currently refactoring goshimmer to support this We are also planning to make the big mana holders publish their opinion in the tangle as a public statement, which allows us to measure the rate of approval in a similar way as multiverse would do it So its starting to converge a bit but we are still using FPC as a metastability breaking mechanism Once the changes are implemented it should be pretty easy to simulate and test both approaches in parallel 📷 Serguei Popov [IF]어제 오후 5:53
So the ask is that we ditch all our work and fork Avalanche because it has not been attacked in the month or so it has been up?
u/NavinRamachandran [IF] yeah, that's hilarious. Avalanche consensus (at least their WP version) is clearly scientifically unsound. 📷 Hans Moog [IF]어제 오후 9:43 u/wtfmaybe you should research avalanche before proposing such a stupid idea and you will see that what I wrote is actually true 📷 Hans Moog [IF]어제 오후 9:44 paying fees is what "protects" them atm and simply the fact that nobody uses the network for anything of value yet we cant rely on fees making attack vectors "inattractive" 📷 Serguei Popov [IF]어제 오후 10:17
well (1.) very obviously the metastability problems are not a problem in practice,
putting "very obviously" before questionable statements very obviously shows that you are seeking a constructive dialogue📷(to make metastability work, the adversary needs to more-or-less know the current opinion vectors of most of the honest participants; I don't see why a sufficiently well-connected adversary cannot query enough honest nodes frequently enough to achieve that)
(2.) .... you'd need an unpredictable number every few tens/hundreds milliseconds, but your DRNG can only produce one every O(seconds).
the above assumption (about "every few tens/hundreds milliseconds") is wrong
We've had this discussion before, where you argued that the assumptions in the FPC-BI paper (incl. "all nodes must be known") are not to be taken 100% strictly, and that the results are to be seen more of an indication of overall performance.
Aham, I see. So, unfortunately, all that time that I invested into explaining that stuff during our last conversation was for nothing. Again, very briefly. The contents of the FPC-BI paper is not "an indication of overall performance". It rather shows (to someone who actually read and understood the paper) why the approach is sound and robust, as it makes one understand what is the mechanism that causes the consensus phenomenon occur.
Yet you don't allow for that same argument to be valid for the "metastability" problem in avalanche,
Incorrect. It's not "that same argument". FPC-BI is a decent academic paper that has precisely formulated results and proofs. The Ava WP (the probabilistic part of it), on the other hand, doesnotcontain proofs of what they call results. More importantly, they don't even show a clear path to those proofs. That's why their system is scientifically unsound.
even when there's a live network that shows that it doesn't matter.
No, it doesn't show that it doesn't matter. It only shows that it works when not properly attacked. Their WP doesn't contain any insight on why those attacks would be difficult/impossible. 📷 Hans Moog [IF]어제 오후 10:56 That proposal was so stupid - Avalanche does several things completely different and we are putting quite a bit og effort into our solution to pretty much fix all of Avalanches shortcomings If we just wanted to have a working product and dont care about security or performance then we could have just forked a blockchaib I am pretty confident that once we are done - its going to be extremely close to the besttheoretical thresholds that DLTs will ever be able to achieve for an unsharded baselayer ------------------------------------------------------------------------------------------------------------- 📷 Bas어제 오전 2:43 Yesterday I was asked how a reasonably big company no one has heard of could best move forward implementing Access for thousands of locations worldwide. (Sorry for the vagueness, it’s all confidential.) They read the article and want to implement it because it seems to fit a problem they’re currently trying to solve. Such moves will vastly increase the utility of protocols like IOTA, and is what the speculation is built on. I do not think you can overestimate what impact Access is going to have. It’s cutting out the middleman for simple things; no server or service needed. That’s huge. So yes, I think this space will continue to growu/Coinnave -------------------------------------------------------------------------------------------------------------- 📷 Angelo Capossele [IF]2020.10.02. In short: we are planning a new v0.3.0 release that should happen very soon. This version will bring fundamental changes to the structure of the entire codebase (but without additional features) so that progressing with the development will be easier and more consistent. We have also obtained outstanding results with the dRNG committee managed by the GoShimmer X-Team, so that will also be integral part of v0.3.0. After that, we will merge the Value Tangle with the Message Tangle, so to have only one Tangle and make the TSA and the orphanage easier to manage. And we are also progressing really well with Mana, that will be the focus after the merge. More or less this is what is going to happen this month. We will release further details with the upcoming Research Status Update📷
Just wanted to say thank you for this sub, because today you kept my MIL from getting scammed out of thousands of dollars. Background: my MIL’s older brother is an expat living in Southeast Asia and married to a woman from that country, whose first language is not English. Their primary source of communication with my MIL is through email due to us being in the US. My MIL’s brother is also career ex-military and often times rather gruff. The story: This morning, my MIL (who lives with us) received an email from her brother requesting she help him pay a bill. He owed someone money and forgotten about it until the day. The problem was, the guy he owed money to requested to get paid in bitcoin, and her brother doesn’t trust their country’s internet to pay him himself. Now, all of these things I’ve explained are all fully in keeping with what could happen with her brother. The gruff form of the email was also explained. And occasionally SIL writes emails on behalf of brother, which explains any spelling mistakes. So my MIL enlisted my husband, who spent the better part of the morning going back and forth from his actual job to helping her figure out how to set up a bitcoin wallet and other things. Something about this whole thing isn’t sitting right with me, and I’m trying to brush it off as worrying about the inherent “shadiness” of bitcoin. Logically, I know a couple people who deal in bitcoin in totally legit ways, but as I hear so many horror stories about it being shady, I’m doubtful. But I don’t say anything. My MIL is clearly stressed worrying about her brother, and my husband is worried about getting it to work, not a potential scam. As the morning goes on, they keep having difficulties, and while talking to my MIL, she mentions things like “he said I can just send him the money with my debit card at an ATM nearby”, and things like that. They’re sending constant emails to each other. Eventually, my husband comes back into the office where I’m working to say his uncle sent a very stern email that said “I expect results. Just let me know when it’s done,” and lamented how his uncle is kind of a jerk sometimes. It’s at this point that I bring up my concerns. He thinks about it, and when his mom comes up to check in shortly afterwards, he says “Are you sure this isn’t a scam?” She also thinks about it too, and agrees to look into it further. Keep in mind, with the time difference between our location and theirs, it’s somewhere in the neighborhood of 3 a.m. their time. About an hour later, my MIL comes back up and tells us she pretended to be having more trouble and couldn’t get the bitcoin to work. Her “brother” then told her she should just buy some ebay gift cards, send him the numbers, and he’d do it himself. DING DING DING! We have a scam! Needless to say, we shut that down immediately and found another way to let her brother know his email had been hacked. BUT it was reading this sub and trusting my gut that saved my MIL from dropping thousands of dollars into this scam. My family is very grateful to all of you!
