Can bitcoin transfer be offline

1.

It can't turn. These are proxy websites, where can I convert currency

according to the 2017 Credit Suisse report, the number of millionaires in the world is about 36 million. Therefore, if a "bitcoin club" composed of users with more than one bitcoin is established, the number of members of the club will not exceed 21 million, less than the number of global millionaires

bitcoin is graally released through the so-called "mining", and today it has issued more than 85% of the total. It's going to get slower and slower, and it's going to stop completely by about 2140. At present, bitcoin's annualized inflation rate (3.7%) is far lower than that of the US dollar since 2008 (36%), and it will further drop to 1.7% after half a day's rection next year

theoretically, one bitcoin can be infinitely subdivided by expanding the precision of digital storage or by upper layer expansion (such as lightning network technology). However, the transfer fee actually limits the value of bitcoin, which is too small. Therefore, the current code only supports subdivision to one in 100 million. The unit calls it "cong", which is named by netizens in memory of the inventor of bitcoin, Nakamoto. Don't say that one bitcoin is too expensive, because you can buy 0.1 or 0.01

bitcoin is in the address. Address is a number, but for the convenience of writing and using, it is encoded into a string form. The bitcoin address is generated by the private key of bitcoin through cryptographic calculation. This generation process does not need Networking (because mathematical calculation does not need Networking), and can be generated offline on your own computer

The account you receive bitcoin is your own bitcoin wallet address. It's different because you have created multiple bitcoin addresses. You can send the bitcoin from the address where you receive bitcoin to your original bitcoin wallet address. Let's take coinbase as an example to illustrate how to use bitcoin Wallet:

< UL >

register

< / UL >

register an account first, which is equivalent to opening an account in a bank. Click sign up in the upper right corner to register an account. Enter your email and password on the registration page to register successfully

then, click accept and continue to accept the agreement

< UL >

receiving bitcoin

< / UL >

after successful registration, you can sign in for account operation. You can select create new address in account settings / bitcoin addresses to select the address of each collection. Click Details on the right side of the newly created account to modify the label to mark the purpose of the address, and save changes to confirm the modification, so that you can clearly know what a certain payment is for

note: the 32 characters in the address are the address of each transaction, which can be sent to the person who wants to transfer bitcoin to you. Or enter the address where you are going to transfer bitcoin to complete the transfer operation. The transfer process may take some time

< UL >

send bitcoin

< / UL >

of course, you can also transfer out bitcoin through send money in send / request. Click send money to enter the destination address (32 strings) in the dialog box, and enter the number of bitcoins to be transferred in the amount BTC. Of course, you can also write some information in the message. Then click the send money button to complete the transfer operation

3. Computers with bitcoin clients are called nodes, and all nodes on the Internet constitute a bitcoin network. Whenever a new bitcoin is generated and traded on a node, the node will broadcast to the nearby bitcoin node, and finally the whole network node will record the transaction information
in the bitcoin network, each node with a client installed has a distributed database to manage bitcoin proction, transaction, query account balance records, and update and record the latest records of changes in the bitcoin system
when you want to send 10 bitcoins to your friends. You need two things, one is the bitcoin address, the other is the corresponding private key. Bitcoin addresses are different from bank accounts. You don't need to sign a bunch of documents to apply for them. They are randomly generated, just a string of letters and numbers. The private key is also a similar string, but this is strictly confidential. The bitcoin address is like a transparent piggy bank. Everyone can see what's in it, but only the person with the private key can open it.
after you send the transaction application, the surrounding nodes will check whether your account has 10 bitcoins. If there are, they will agree to the transaction, and broadcast the message to the nearby nodes, which will be transmitted from one to ten, and from ten to 100, Soon the whole network will confirm the transaction information and write it to the block. Your friend will receive 10 bitcoins, and the transaction will be completed.
if you want to send small bitcoins, in theory, digital currency can be cut infinitely. At present, the smallest bitcoin unit is called "Nakamoto Tsung", which is equivalent to 0.00000001 bitcoins.

4. In the legal currency system, each country has a strict clearing and settlement system. For example, inter-bank transfer and non local transfer will take a long time to wait or have high handling charges. Especially in foreign exchange transactions, there are strict controls on foreign exchange transactions between countries. None of these rules exist in the bitcoin network. You only need to send a transfer request gently, and it can basically arrive in an hour.

9. The answer is quite a few, but not many to the point
the motherboard supports PCIe × 16, the problem is not big, in theory, the mainstream of the lower end graphics card can be used. But considering your weak small power supply, 96gso can be directly ignored. The rating should be more than 230W. The TDP of your original whole system is about 200W. Is the rating 230W? Brand machine in this respect usually (I mean usually ~ ~) will not shrink, the rating should be above 250W. The old 65nm and 55nm cards will not be considered. We recommend the enhanced version x2
of YinChi GT220 http://detail.zol.com.cn/vga/index216225.shtml
tdp60w is not available, so it is affordable and the price is reasonable
the performance is better than 95gt and 4650, slightly inferior to 96gso G94 and HD4670. It's enough for your U. And this kind of low-end small card, the size will not be very big, card body is quite short, HTPC small chassis is no problem, you can absolutely plug in.
