BTC recharge PayPal
it was originally a kind of network virtual currency, similar to Tencent's q-coin, but it can already buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan.
Yes. Click buy on the bitcoin trading website and choose PayPal when it comes to the payment method. Now PayPal supports bitcoin trading
purchase process:
1. The first step is to enter China's bitcoin trading platform and register
2. The second step is to register successfully. After login, you can buy and sell bitcoin. Under the transaction function, you can buy and sell bitcoin, manage the entrustment and query the transaction operation. Under the account management, you can transfer in and out bitcoin and transfer in and out RMB
The third step, RMB recharge and cash withdrawal support a variety of ways, the handling charge is relatively high, and the limit and handling charge of each way are different 
4. The transfer in and transfer out of bitcoin refers to the transfer of bitcoin between the trading platform and the bitcoin wallet. The bitcoin wallet needs to be downloaded from the bitcoin official website. After downloading and installing, it needs to synchronize the data. The current data packet is about 8.5g, which takes a long time to synchronize. For friends with a small amount of investment, it can be skipped
5. After the installation of bitcoin wallet, there will be a default acceptance address. When the transaction platform withdraws bitcoin, you can paste the address. Recharge is a reverse operation. The transaction platform will give you an address to send money in the wallet and paste the address
the transaction of bitcoin needs to pay a certain handling fee. The handling fee of bitcoin China is 0.3%, which is equivalent to the upper limit of the Commission for stock transaction. In the trading platform, there is the latest trading data, also can refer to btc123, the market data is more intuitive. Bitcoin trading is different from securities trading. There is no limit to the rise and fall of bitcoin, and it trades 24 hours a day. The whole market plate is small, and it is easy to be controlled by the makers, and it may also be attacked by hackers. Therefore, the risk is huge. It is recommended to invest cautiously. Novices had better understand the relevant concepts first
Yes , the price of bitcoin has skyrocketed , and now it has exceeded $40000, a record high< the continuation of this trend makes many players rush to buy more mining machines . At present, the price of bitcoin mining machines has doubled, but the supply still falls short of demand , which makes people feel that the "sale of mining machines by catty" at the end of 2018 has completely become a thing of the past
it is reported that in Shenzhen Huaqiangbei SEG market, a miner shop salesman said that the price of miner doubled within two months, but the supply still exceeds the demand, "it depends on whether you have the source of goods."

extended information
recovery of old bitcoin Market:
the shortage of supply of the latest generation of bitcoin miners not only triggered a bidding war, but also revived the old bitcoin market. In view of the recent price rise, miners have announced the quotation of antminer S9 or Avalon 851, the equivalent model of Jianan Yun, with the price range of US $80 to US $130 per unit. By contrast, such models were liquidated for less than $50 at the end of China's peak season last October
e to the continuous expansion of mining income and the parabolic rise of bitcoin price, more and more people are mining on a larger scale than ever before. According to the block & 39; Bitcoin miners' revenue per trillion second of computing power has reached its highest level since September 2019 e to soaring prices, according to s data dashboard
and paypal
shopping. Now I will give you some answers to these questions. 1、 How to recharge paypal
in China, neither credit card nor bank card can recharge US dollars or RMB into PayPal account (the state's foreign exchange control is relatively strict). Only local banks in the United States (not even foreign banks in China) can recharge US dollars into PayPal account, which is why there are market conditions for PayPal exchange business
although you can't recharge US dollars into your PayPal account in China, if you want to shop online abroad or remit money to your relatives and friends abroad, you can bind (authenticate) an international credit card through your PayPal account. After authentication, you can directly purchase or remit money to the PayPal account of your relatives and friends abroad through your credit card. PayPal can withdraw money directly from ATM abroad
here, I would like to remind you that only the local bank in the United States can directly recharge the U.S. dollar into the PayPal account, and the bank account of the U.S. bank opened in China can not recharge the U.S. dollar into the PayPal account, which should be paid special attention to. The main reason is that our country has strict control over foreign exchange
there is another way to solve the problem of not recharging the PayPal account to the US dollar. It is through finding a person to exchange PayPal dollars (using RMB in a certain proportion), the other party pays the US dollar through your PayPal account to your PayPal account, and you send the remittance through Alipay or domestic bank to the right side, so as to solve the problem of recharging the PayPal account to the US dollar. 2、 How to recharge your PayPal account in US dollars and RMB
currently, only local banks in the United States can recharge their PayPal account in US dollars (for example, the Bank of America account you applied for in Shanghai can't recharge your PayPal account), and your PayPal account can't recharge RMB. Third, when you shop online with PayPal, PayPal has enough balance, but the other party requires you to pay with PayPal credit card, What if I don't have a credit card
you can use the method of "payment on behalf" to find a professional PayPal agent to pay. You pay the Commission to the agent, and the other party pays for you
friendly reminder: you need to find a reliable agent for this kind of payment.
