What is the upper limit of bitcoin to avoid

1. 1. The number of bitcoin is limited, because the original intention of the design is to have a currency with a fixed circulation, so that the final number can not be increased or decreased, so as to eliminate the inflation and deflation risks caused by man-made money printing. The specific number is determined according to the block and block reward principle:
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.

2. According to the legendary algorithm, bitcoin has an upper limit of 21 million. But you know the algorithm. Although it's very difficult to make adjustments in theory, if you (the legendary top trading institutions with trillions of wealth) really want unlimited, it's a matter of minutes

theoretically, 2100 trillion, or 250.899. In terms of selecting this value, this number is far less than 264-1, which is the largest integer that can be stored in the form of standard integer in a computer. If it exceeds that value, the bitcoin value will return to zero like a odometer

but this is only theoretical, just theoretical. Just like the previous IP address regulations, no one expected that V4 would be used up so quickly. Now it is necessary to use V6. This so-called "maximum integer that can be stored in the form of standard integer" may be broken by the technology upgrade one day a year later, followed by the collapse of the whole bitcoin computing.

3. The upper limit of bitcoin is not the exact figure of 21 million. 21 million is calculated according to the mining rules
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

4. There is no threshold for bitcoin investment, and anyone can participate in it. The advantages of bitcoin are as follows:
freedom of payment - you can pay and receive any amount of money anytime and anywhere. No bank holidays, no borders, no imposed restrictions. Bitcoin allows its users full control of their funds
very low fee - at present, there is no or very little fee for the processing of bitcoin payment. The user can include the service charge in the transaction to obtain the processing priority and receive the transaction confirmation from the network faster. In addition, there are also merchant processors to assist merchants in processing transactions, converting bitcoin into legal tender every day and depositing the funds directly into the merchant's bank account. Because these services are all based on bitcoin, they can offer much lower fees than paypal or credit card networks
rece business risk - bitcoin transactions are secure, irreversible, and do not contain customers' sensitive or personal information. This avoids the loss of merchants e to fraud or fraulent chargeback, and there is no need to comply with PCI standards. Where credit cards are not available or where fraud rates are unacceptably high, businesses can easily expand into new markets. The end result is lower costs, larger markets, and less administrative costs
Security and control - bitcoin users have complete control over their own transactions; It is impossible for businesses to impose fees that may occur in other payment methods that should not be or are not easy to find. Payment with bitcoin can avoid binding personal information in the transaction, which provides great protection against identity theft. Users of bitcoin can also protect their funds through backup and encryption
transparent and neutral - all information about the bitcoin funding itself is stored in the block chain and can be verified and used by anyone in real time. No indivial or organization can control or manipulate the bitcoin protocol because it is password protected. This makes the bitcoin core believed to be completely neutral, transparent and predictable
of course, digital currencies such as Ruitai coin, Qianjin card, Laite coin and doggy coin also have these advantages, but their acceptance and popularity can't be compared with bitcoin.

5. Triporg travel: a travel service application using blockchain, which provides booking services such as air tickets and train tickets.

6. No, only financial constraints on your purchase
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

7. There is an upper limit to the number of bitcoins, mainly because there is an upper limit to the solution set of the algorithms involved in the program. The algorithm is very complex. In theory, no computer has such powerful computing power that it can solve 51% of the solution set, that is, no one can control bitcoin

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.

8. The upper limit is 21 million. The solution to this problem is divisible. That is to say, you can take 0.0001 BTCs or 0.002 BTCs. Because of its divisibility, you don't have to worry about it. You can be sure that there will be less and less bitcoins in the end. Because of the loss, there will be more and more missing bitcoins for various reasons

9. It's true that there is a threshold, but it's too low. For example, the okex exchange I use can buy bitcoin for at least 10 RMB. It's not too much to say that there is a zero threshold.

10. There is an upper limit to the total amount of bitcoin. The inventor of bitcoin has explained that.
