1. You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. 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 about 21 million
2. 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.
3. The method is to turn bitcoin client into green version, but it may have unpredictable problems to open it at the same time, so please experiment with small wallet first. The green method is to run the client exe with shortcut and parameters, bitcoin-qt.exe - dataDir = e: &# 92; Bitcoin, = followed by the path of the database folder. The default location of the database folder is% appdata% & # 92; Bitcoin added: because the wallet file is located in the database folder, so to open more at the same time, you need two database folders to put the wallet file in, and it's better to two client folders to run separately. In this case, I don't know if there is any risk in the transfer. Let's experiment with it.
4. How to choose BTC wallet and how to store your bitcoin? This is an important problem that every bitcoin user must face. Bitcoin gives you more freedom and power to control your money. But if you are not careful, it may bring disastrous losses. If you choose to remain in complete control of your bitcoin on your own, then there is no one who can stop you from doing something stupid and pay for your mistakes. There is no bitcoin company to call and try to convince your legitimate owner of your address so they can give you the key back. However, there are friendly and secure services based on bitcoin, or intermediate solutions, which can let users avoid the risk of operating wallets. The purpose of this article is to explain what different options you have for storing BTC, so that each user can make the right choice between security and control. Wallets fall into two main categories: Online wallets online wallets are by far the easiest way to access your bitcoin from any computer. But there needs to be enough trust in wallet service providers. Currently, there are four main choices for online Wallet:
5. If you want to contribute to the bitcoin network, it's a good choice to run a full node to synchronize the block data; If you just want to use bitcoin, you don't need a full node wallet at all. You just need to install a new wallet. The better one in China is the coin pack.
6. At present, the data capacity of bitcoin
blockchain continues to grow. Now it's about 10g. When many friends install the system, Disk C is not set very large. Are you worried that disk C will explode one day. Now learn how to do data migration with me First, close bitcoin client)
1. Find bitcoin's data folder< br />
XP---C:\ Documents and Settings\ username\ Application Data\ Bitcoin
vista,win7---C:\ Users\ username\ AppData\ Roaming\ Bitcoin
(Note: appdata is hidden, set to show hidden files.)
2. Cut this bitcoin folder to other drives with large space, such as disk E
3. Edit the bitcoin shortcut on the desktop, the following line to the "target" column, and then save it:
& quot; C:\ Program Files\ Bitcoin\ bitcoin-qt.exe" - datadir=e:\ Bitcoin
now, double-click the bitcoin shortcut on the desktop, the client will start, and your C disk will be saved, releasing space successfully.
7. Imtoken doesn't have BTC wallet, it can only store erc20 token
8. The wallet address represents your different wallet. After the computer reloads the program, it will automatically generate a new wallet address. Of course, it is different every time. If you only want to use one wallet, you just need to export your wallet address. Next time you reload the system or the wallet program (or install it on other computers), you can import the address or create a new address manually
good luck!!!
9. Take no.323 or No.24
