PHP makes virtual currency transactions

1.

Here are some personal experiences in the exchange

(1) the coin search website has the advantages of low service charge, quick withdrawal and multiple currencies. It supports a variety of well-known virtual currency transactions and is convenient to purchase usdt. It has app and high security

(2) kucoin overseas version (coin win background) has smooth interface operation, and the speed of coin withdrawal is not bad, but most of them are junk ICO coins, many names have not been heard of, such as app

(3) China bitcoin overseas version EXX (slow coin withdrawal, kengdai) gambling platform, fixed-point blasting futures pop you up, there seems to be a problem with cash withdrawal, no app

(4) fire coin overseas version, Collude with OK, dozens of junk money a week, no bottom line, many small problems. Support C2C transactions, there are app

(5) okcoin overseas version, this does not say, OK life black, although support C2C transactions, but bottomless line shelf circle coins, flicker leeks, C2C transactions can not be withdrawn, embezzle the user's assets after the decimal point of tens of millions, careful into

(6) BTCC overseas version, support us dollar UnionPay direct charge, but the handling charge is high, it is relatively low-key in China, The experience of the transaction interface is very poor

(7) the overseas version of cloud coin has few currencies and many problems, so it's all warriors

(8) currency security is currently the largest exchange in China, with the most complete currency and many activities. It doesn't card you to withdraw and recharge money. Although there are so many junk money in ICO, it doesn't have as many problems as hot money OK platform. It can be said that it is the best exchange in China. It has app, needs to turn Q, and mobile client doesn't need to turn Q

(9) Yuanbao overseas version has Canadian financial license, legal operation, insufficient depth, small amount of currency, small transaction volume and insufficient UI beautification

(10) in the bitage, the overseas version takes a very long time to review, and it takes you a long time to pick up the coin and issue the coin. The miner's fee used to be a little higher, but now it's just a little higher. 0.5% for recharge, 1% for withdrawal, and the highest withdrawal fee in the whole universe. The garbage made by the K-line chart can't hold on to the ICO coin. At present, this platform can't stand the temptation of interests, and the card is only issued half a day, The trading volume is a little less. At present, I have abandoned this platform

(11) the overseas version of China's bitcoin has just been opened for trading, and C2C trading has a unique qash trading area. There are many small problems, so be careful to enter

2. When choosing the registered account number of each mainstream exchange, trading in legal currency for TEDA currency, trading in other currencies through TEDA currency, the general website has a detailed process.

3. Virtual currency mainly refers to the overseas market, so it is necessary to have an overseas bank account for virtual currency trading. At present, the most practical one is the Hong Kong bank account, which is not explicitly prohibited in Hong Kong, so it can be operated as long as the transaction complies with the bank regulations
of course, the Bank of Hong Kong can not directly open an account in the past, Banks in Hong Kong are no longer afraid of money laundering and fraud. They are domestic accounts
the landlord really wants to open a Hong Kong bank account, which we can help you to open successfully. The information is simple

4. First of all, we should be careful to keep a clear mind, and then we should pay attention to all kinds of problems all the time. However, the most important thing is that the platform must be highly transparent, and formal platform is better than anything

5. The conditions for handling virtual currency transactions should be as follows:
1. Enterprises are not allowed to operate both virtual currency transactions and virtual currency issuance businesses at the same time
2. The conditions for handling virtual currency transactions should meet the relevant conditions for establishing operational Internet cultural units
3. The transaction conditions of virtual currency should meet the relevant conditions for the establishment of operating Internet cultural units, and the relevant provisions of the competent department of Commerce on e-commerce (platform) services.

6. It is not illegal for e-commerce companies to do virtual currency exchange, and it is not illegal to invest in virtual currency. But how to get involved in virtual currency transactions is illegal and illegal. It may be suspected of illegal fund-raising
moreover, these so-called virtual currencies are basically empty handed projects with white wolves, and the application scenarios of their publicity are also non-existent and unreliable. These currencies are different from the mainstream digital currencies such as Ruitai, bitcoin and Leyte.

7. According to your needs, the customized virtual currency trading system Shengshi Huacai is still good, mainly for customized service and lifelong maintenance, which has a history of 13 years and is trustworthy.

8. Why not dig bitcoin BTC instead of bitcoin VTC? At present, many large-scale mines abroad have allocated one third of their computing power to dig special coins. What is the reason for this
let me analyze it:
1: bitcoin has been broken in China, and its price has dropped sharply, which is unexpected by the global mining pool
2: compared with the current mining cost of bitcoin, it makes money entirely by cheap electricity bills
3: there are only 21 million bitcoins, and most of them have been g up in the early stage, which makes it difficult to dig those bitcoins that have not been g up in the future, and there is too much competition. Many small mines are in a state of loss
and why do many well-known mines turn to TCD
first of all, bitcoin is the optimized and upgraded version of bitcoin, with a constant number of 100 million. The early mining is very good. Unlike bitcoin, which has too high cost and low cost performance ratio, it is appropriate to use bitcoin as a supplement to compare bitcoin. Bitcoin is used for large amount payment and bitcoin is used for small amount payment.
