Buy a miner and dig by yourself

1. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.

2. Why is bitcoin so valuable? The reason why issuers don't sell bitcoin themselves or others dig bitcoin is the same. Only when the demand is high enough can there be enough market. If there is no market, it is a piece of shit. not to be worth a hair

3. Now the mining machine is generally not big, and the computer host should be smaller. Mining needs to be added to a mine pool, which cannot be g by itself. Now mining has been close to or even more than the currency price, if the electricity charge is free, you can go to mining. Mining power is very large, and you need to install refrigeration equipment. The noise is also very loud. You should also pay attention to this. The noise of the miner of ants is relatively small. The ant miner is OK. If you buy a miner, don't buy a second-hand miner. It's not worth it. The miner's update speed is amazing. If you don't understand, please send me a private letter.

4. Bitcoin is a winner take all, and you can only get profits if your computing power reaches a certain level. Therefore, it is suggested that ordinary retail investors should find a reliable exchange, such as okex exchange, to purchase directly.

No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law

transaction mode

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

See a lot of people selling bitcoin mining machines, why don't they go mining? Do they make more money selling machines than digging bitcoin

On the gold road, the most profitable is the ticket. Those who dig money are all gold miners. Mining machine manufacturers are those who sell water and shovels on the way to gold mining. The so-called saying is that they have heard the news one after another, and they specialize in the technology instry. It's OK to do a good job in their own specialty. They can't earn any money

the purpose of enterprises is to make money. Since selling mining machines can make money, why should they be involved in the mining instry. Wu Jihan in mainland China is worth tens of billions of yuan only by selling mining machines, and he is engaged in large-scale mining in many countries. It's also very limited. Since selling equipment can make money, why do you have to mine

another example is the e-commerce instry. I don't know whether it makes money or not, but I know that agent operation must make a lot of money. Now the hot small program, businesses through small programs to earn money, I do not know, but those who help develop small programs companies must make money

7. Bitcoin mining is not illegal, as long as you use your own money, then you don't have the law to buy the ore. mining bitcoin mining is not illegal, as long as you use your own store and your own money, then you are not protected by law to dig the ore.

8. It can be understood as a kind of distributed computing, but I don't think it can be called & quot; Paid & quot;, The key of bitcoin is to admit the value of the code, As long as the bitcoin system does not collapse, those who accumulate bitcoin can profit from the fluctuation of the value of bitcoin and real currency
hope to adopt it
