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.
From the current technology, the next bitcoin in the bitcoin data structure can be divided into 8 decimal places, so the minimum unit of bitcoin is 0.00000001btc, but the transaction can not be so small
according to the statistics of bitbao, at present, the common minimum trading unit of bitcoin trading platform in China is 0.01btc, so the 0.0001 proposed by the owner is not available for sale< br />
3. 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.

4. 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

5. Triporg travel: a travel service application using blockchain, which provides booking services such as air tickets and train tickets.
6. The credit problem of central system
7. The minimum unit of bitcoin is 8 digits after the decimal point. Generally, exchanges can buy 6 digits after the decimal point,
that is, the minimum number is 0.000001. You can try it
now all exchanges are absorbing new users, and the operation is relatively friendly

8. Online banking of Bank of communications has the function of settlement and sale of foreign exchange, but it must open the registered version of online banking, SMS version / certificate version. It can exchange RMB and foreign currency in financial management, but it is not real-time. There will be an approval process, but it will be very fast.
9. 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

10. 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.
