Does bitcoin have a lower limit

1. There is no limit to the range of rise and fall.

2. 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

3. 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.

4. 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.

5. No, the total amount of bitcoin is constant. There are only 21 million bitcoins in total, which are determined by the program. No one can tamper with them. Even the founder, Nakamoto Tsung, can't issue additional bitcoin. That's why so many people compare bitcoin to digital gold.

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. 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.

8.

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

9. I don't think so, but at least it costs a few hundred yuan
