It's worth noting that it is projected to take more than years before the Bitcoin network mines its very last token. In actuality, as the year approaches, miners will likely spend years receiving rewards that are actually just tiny portions of the final bitcoin to be mined. The dramatic decrease in reward size may mean that the mining process will shift entirely well before the deadline.

It's also important to keep in mind that the bitcoin network itself is likely to change significantly between now and then. Considering how much has happened to Bitcoin in just a decade, new protocols, new methods of recording and processing transactions, and any number of other factors may impact the mining process. The latest significant events are the Office of the Comptroller of the Currency OCC letter in January authorizing the use of crypto as a method of payment, Paypal's introduction of Bitcoin, and Tesla's acceptance of Bitcoin to purchase Tesla cars and solar roofs.

Key Takeaways There are only 21 million bitcoins that can be mined in total. However, you can always buy bitcoins from existing users on exchanges.

Yes, there are only about And there will only ever be 21 million in the future. There's no exact answer. One recent estimate is that about million bitcoins are lost forever. It is impossible to know an exact number since a lost Bitcoin looks exactly the same on the blockchain as one that is not lost. We can make some educated guesses based on how long a Bitcoin has sat in an addresses unmoved. The truth is, no Bitcoin is really "lost" as much as it is permanently locked away.

We know where all the Bitcoins are. When we say a coin is "lost", it is sort of like saying someone locked the coin in a box and lost the key to the box. And this box is impossible to open without the key. Investments are subject to market risk, including the loss of principal. Because many miners are adding new hashpower, over the last few years blocks have often been found at 9. This creates new bitcoins faster, so on most days there are actually more than new bitcoins created. Since bitcoins can only be created by being mined, all the bitcoins in existence are all bitcoins that have been mined.

The total is BTC. We have guides on how to buy bitcoins and how to get a wallet.

Some estimate Satoshi has around , bitcoins BTC. This number is heavily debated, though, as some claim he has around , BTC. Gox hack , which was the largest Bitcoin hack ever. Another , BTC were stolen from Bitfinex in Together, that adds up to about , BTC. It's likely these stolen coins are still circulating, and may not even be in the hands of the original thieves. It's impossible to know exactly. With some quick math, however, we can estimate the max number of people who are Bitcoin millionaires.

Since there are BTC in circulation, there are a maximum of people holding bitcoins. Instead, your bitcoin wallet and the bitcoin network have to go through a set of steps to ensure that the right amount of electronic money gets to the recipient. Instead, it is basically a file referred to as money hereafter with a value that registers as a transaction when you initiate a payment or receipt. There are three elements involved in a bitcoin transaction: a transaction input, a transaction output, and an amount. The transaction input is the bitcoin address from which the money was sent, and the transaction output is the bitcoin address to which the money was sent.

If the bitcoin is in your wallet , that will be the bitcoin address under your control. The bitcoins that you send to someone were sent to you from someone else.

When they sent them to you, the address that they sent it from was registered on the bitcoin blockchain the encrypted and unaccessible register as the transaction input, and your address—the address they sent it to—was registered on the bitcoin network as the transaction output. That transaction will then be registered on the bitcoin network with your bitcoin address as the transaction input. Using this system, people can trace bitcoin transactions all the way back to when the bitcoin was first created, understanding who sent it to who at any point in time. This creates a completely transparent system in which all transactions can be checked at any time.

One problem with bitcoin is that the amount attached to these transactions with their inputs and outputs isn't divisible. For example, if Alice has a bitcoin address with one bitcoin in it, and she only wants to send Bob half a bitcoin, then she would have to send Bob that entire bitcoin. The bitcoin network would then automatically create 0. That third address will also be a transaction output, meaning that the address will have multiple transaction outputs. Over time, this means that bitcoin wallets end up with lots of addresses containing varying amounts of bitcoin and change from bitcoin transactions.

When you send bitcoins to someone, your wallet will try its best to piece together the necessary funds using the addresses containing the different amounts. That leads to transactions that can have several different inputs—different addresses with different amounts used to make up the funds. What if you want to send just a tiny amount of bitcoin?
