How Many Bitcoins Are There Now in Circulation?

There are currently bitcoins in existence. This number changes about every 10 minutes when new blocks are mined. Right now, each new block adds 6.25 bitcoins into circulation.

How Many Bitcoins Will Ever be Created?

The maximum and total amount of bitcoins that can ever exist is 21 million.

How Many Bitcoins Are Left to Be Mined?

There are bitcoins left to be mined.

How Many Bitcoins Are Lost?

There's no exact answer. One recent estimate is that about 3-4 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.

By looking at the age of all UTXO's we can make some educated guesses about which coins are "lost" or "stuck"

We also have media reports of large wallets where the owner claims to have lost the private key.

Stories like these are common and by knowing about them we can keep an informal minimum tally on lost coins

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.

How Many Bitcoins Are Mined Everyday?

144 blocks per day are mined on average, and there are 6.25 bitcoins per block. 144 x 6.25 is 900, so that's the average amount of new bitcoins mined per day.

Mining is the method through which Bitcoin is secured

Because many miners are adding new hashpower, over the last few years blocks have often been found at 9.5 minute intervals rather than 10. This creates new bitcoins faster, so on most days there are actually more than 900 new bitcoins created.

How Many Bitcoins Have Been Mined Already?

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.

How Many Bitcoin Blocks Are There Today?

There have been blocks mined.

We have guides on how to buy bitcoins and how to get a wallet.

How Many Bitcoins Does Satoshi Have?

Some estimate Satoshi has around 900,000 bitcoins (BTC). This number is heavily debated, though, as some claim he has around 300,000 BTC. You can read our write up on Satoshi Nakamoto's Net Worth as well.

How Many Bitcoin Have Been Stolen?

It's unclear exactly how many bitcoins have been stolen.

850,000 BTC were stolen in the Mt. Gox hack, which was the largest Bitcoin hack ever. Another 120,000 BTC were stolen from Bitfinex in 2016. Together, that adds up to about 970,000 BTC.


Stolen BTC, however, does not mean lost BTC. It's likely these stolen coins are still circulating, and may not even be in the hands of the original thieves.

How Many Millionaires Were Made From Bitcoin?

It's impossible to know exactly. With some quick math, however, we can estimate the max number of people who are Bitcoin millionaires.

One of many VERY young Bitcoin Millionaires

With Bitcoin's price at $, you'd need bitcoins to be a Bitcoin millionaire in dollars. Since there are BTC in circulation, there are a maximum of people holding bitcoins.

In all likelihood, the number is much lower than that and probably around 30,000-60,000 people with more than $1 million worth of bitcoins.

How Many Bitcoin Miners Are There?

Slushpool has about 200,000 miners. They have 12% of the network hashrate. Assuming all pools have similar numbers, there are likely to be over 1,000,000 unique individuals mining bitcoins.

We can also look at the hashrate to make some rough assumptions about how many miners there are.

When Will the Last Bitcoin Be Mined?

The short answer is: likely sometime in 2140 when the last Bitcoin halving is expected to occur.

As you can see, Bitcoin supply decelerates over time until it hits 0 in 2140

It is hard to know for sure, though. New blocks are added approximately every 10 minutes. The further out we try to predict when specific halvings will occur, the harder it is. Over 120 years, a lot can change, and so it may happen sooner or later, perhaps even by more than year.

What Will the Block subsidy (reward) be before going to 0 BTC?

The block reward will be a mere 0.000000011641532 BTC per block. Currently the block reward is 6.26 BTC. There are 30 more halvings before it goes to 0. If we divide 6.25 by two 29 times, then we get 0.000000011641532.

What Happens When All 21 Million Bitcoins Are Mined?

Right now, miners earn most of their income via the block reward. When all 21 million bitcoins are mined, there won't be a block reward to pay to miners.

When a Bitcoin user sends a BTC transaction, a small fee is attached. These fees go to miners and this is what will be used to pay miners instead of the block reward.

How Many Bitcoins Will Be Mined Before The Next Halving?

There are BTC left to be mined until the next block reward halving.

How Many Bitcoin Billionaires Are There?

With Bitcoin prices hitting around $10,000 US dollars, there may not be many Bitcoin billionaires. The Winklevoss twins are Bitcoin billionaires while the price is above $10,000, since they own more than 100,000 BTC.

How Many Litecoin Are There?

At the time of writing, there are a little over 57 million litecoin (LTC) in existence. The Litecoin block halving is projected to be in August 2019.

Is Bitcoin Issuance Similar to Gold?

Gold's supply has historically increased at around 2% per year. Bitcoin's supply will increase less than 2% starting at the 2020 halving, and will eventually go to less than 1% a year after the 2024 halving.

Bitcoin vs gold will be a big debate in the coming few years.


How Many Coins Copied Bitcoin?

Most coins are exact copies of Bitcoin's source code. Bcash is a fork of Bitcoin with a few things taken out. Litecoin is also a fork of Bitcoin with the block time and mining algorithm changed.

How Many Ethereum Are There?

There are a little over 100 million ether (ETH) in existence. There is no real cap on the total number of ETH than can come into existence like there is with Bitcoin. Eth is not a fork or clone of Bitcoin like Litecoin is.

How Long Does it Take to Mine a Bitcoin?

New bitcoins are mined every 10 minutes. The amount of time it takes a miner to mine a bitcoin will depend on how much mining power he has.

Who Has the Most Bitcoins?

As discussed above, it's likely that Satoshi has the most bitcoins of anyone.

How Long Has Bitcoin Been Around?

Bitcoin has been around since 2009. You can see the tiny amount of data included in that first block below:
