Is the number of bitcoins up to the limit
The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

monetary characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform mining: users can explore the computing power of different hardware on many platforms
the assumption is that six data blocks can be generated every hour in the world, and 210000 data blocks can be generated every four years; Then it makes a decreasing payment for the return of data blocks, 50 bitcoin for each data block in the first four years, 25 bitcoin for each data block in the second four years, 12.5 bitcoin for each data block in the third four years, and so on... Finally, the total number of bitcoins is -
210000 x (50 + 25 + 12.5 + 6.25 + 3.125 +...) = 21 million
the cumulative sum in brackets is close to 100 and will never exceed 100, so the total number of bitcoins is 21 million
currently in the second four-year period, each calculated data block contains 25 bitcoins
2. There is no loss of wealth. Many people at home and abroad are digging for bitcoin, and they are also speculating in bitcoin. Computer and Internet speed can only determine the speed of bitcoin digging, but not the value of bitcoin. Even if you say that we dig abroad, we fry. Now we buy a bitcoin for $300, and there will be no bitcoin to dig in the future. Maybe a bitcoin will sell for $3000, and then we sell it again, won't we make a profit? Where is the loss of wealth? Of course, maybe a bitcoin will be worth $3 at that time. Who can say that it is not born by the central banks
3. In addition to bitcoin, there are several similar virtual currencies such as lightcoin. However, they all adopt similar design principles. Therefore, in the future, there will inevitably be a problem that the currency will eventually be widely recognized, and other currencies that are not recognized will be eliminated. Otherwise, a new virtual currency can pop up at any time. It's not the same as printing money, which completely goes against their original design intention.
21 million. Now the price of bitcoin is almost 70000
in the first four years, 50 pieces were g out every ten minutes: 50 * 6 * 24 * (365 * 4 + 1) = 10519200 pieces
in the second four years, 25 pieces were g out every ten minutes: 25 * 6 * 24 * (365 * 4 + 1) = 5259600 pieces
according to the sum formula of infinite equal ratio sequence, the final total amount is infinitely close to 21038400 pieces (10519200 * 2)
as long as the mining rules are not changed, the number of bitcoins will never exceed 21038400
the risk of all financial procts is that after the depreciation of the financial procts, they may not appreciate or return to the price when you bought them on time
that is, your property is trapped in it, and you are unwilling to sell it after devaluation. Wait, I don't know that you can't get it back until the end of the year. Maybe, just like China's stock market, you can't stop losing. The more you wait, the more you lose
so far, the number of bitcoins has reached 12 million. To be exact, the maximum number of bitcoins should be 2099990000, but in fact, the current mining (mining) process is quite difficult - no less difficult than connecting 1000 home computers, and then continuously calculating for a month, it is not possible to dig out a bitcoin
I hope I can help you.
In the algorithm of bitcoin, the generation of new bitcoin is limited by period and quantity. According to the algorithm, 50 bitcoins will be generated every 10 minutes from the beginning, and the efficiency will be halved every four years. By 2140, 21 million bitcoins will be completely g up
As a popular new currency, it is publicly prohibited in many countries, but there are still unfair transactions in some countries, including Tesla's bitcoin gene exchange. In a few hours, the 18 millionth bitcoin will be mined, which is also the first cryptocurrency in the world. It's a step up to 20 million{ RRRRR}
one of the difficulties for the current global graphics card is caused by bitcoin, because many bitcoin mine owners used to mine it to obtain benefits., As a result, they buy a lot of equipment, including a lot of electricity, to dig, which is a blow to a global instry
