How many Bitcoin Are There #Bitcoin

Is there a limited amount of Bitcoin?Yes, there are only about 19.1 million Bitcoin in existence. And there will only ever be 21 million in the future.

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.

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.

Because many miners are adding new hash power, 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 19,986,406.25 BTC.

How Many Bitcoins Does Satoshi Have?

Some estimate Satoshi has around 1,000,000 bitcoins (BTC). This number is heavily debated, though, as some claim he has around 300,000 BTC.

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.

With Bitcoin's price at $84232.96, you'd need 11.87 bitcoins to be a Bitcoin millionaire in dollars. Since there are 19,986,406.25 BTC in circulation, there are a maximum of 1,683,514 people holding 11.87 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?

When Will the Last Bitcoin Be Mined?

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

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 Bitcoin Billionaires Are There?

With Bitcoin prices hitting around $23,000 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. So they are well beyond Bitcoin billionaires!
