Why don't you use the official BTC wallet

1.

I use my wallet, of course

this is the wallet interface

2.

bitcoin is a kind of P2P digital currency

reasons for blocking:

1. Vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities

The transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed

The price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading

4. The public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation

the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner

This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees

3. The essence of BTC is a distributed, algorithm-based and public network account book (just as the essence of a bank is a private account book which is not publicly controlled by the central government). The wallet (private key) is actually the right for you to modify the account number (public key or bitcoin address) in the account book. The wallet corresponds to the account number. In fact, the specific wallet file contains more than one private key information, which can be copied to other places for use. As long as you have the private key corresponding to the account, it's like having the password of the bank card. Understand the above, you should also understand the answer to your question - B has 10btc on the address. It's not about the computer. This may be better understood by you: wallet = private key (bank card password) + public key (bank card number) BTC network system = Bank, access to BTC network with wallet = bank card inserted into ATM and certified, payment = transfer to other accounts.

4. Because bitkeep's R & D team has a very strong background. Although it has a short online time, it has already supported four main networks BTC, ETH, Neo and ont. As long as the currencies on these four main networks, bitkeep can support them. Other wallets may only support one or two main networks, and all supported currencies are limited.

5. I have been using okex's Multi Chain Wallet, because I buy more than one kind of bitcoin, so I can manage n cryptocurrencies at the same time with okex wallet, which is very convenient. I hope my answer can help you, thank you very much!

for example, European crowdfunding chooses to use blockchain technology to serve the real economy and crowdfunding through blockchain technology. Ethereum launched an intelligent contract system; Decent uses blockchain technology to protect intellectual property rights.

9. Today's young people are no longer speculating in gold, they are speculating in virtual currency represented by bitcoin. Moreover, the purse is very convenient, the operation is free, and the exchange rate of bitcoin is relatively high. This is a new investment mode.

10. No, remember to back it up after installing the wallet. If you don't back it up, the computer will have problems or the wallet will be deleted. The bitcoin in the wallet may not be found. It's very troublesome to retrieve it. If you want to be more secure, you can store the bitcoin wallet in a computer or USB flash drive that you don't often use, which is the so-called cold wallet

in fact, I suggest that if you don't know much about the basic knowledge of bitcoin wallet or have no technical background, you should not store bitcoin in your downloaded wallet. Now the technology of online wallet is quite mature. You can store bitcoin in online wallet, which is simple, convenient and safe. Of course, you can also find a bitcoin payment company to help you receive bitcoin

there are some bitcoin wallet installation tutorials on bitcoin home. You can learn about them.
