Free virtual currency

1. bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. 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

2. The following is an example of bitcoin mining:
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary
however, most of the new digital cryptocurrencies after 2016 do not need mining, and most of them use POS mechanism, and some of them are one-time mining, such as Ruitai.

3. You first go to the official website of virtual currency to have a look, and then you have to consider how large scale the investment in large mines is, and the income is also very huge. If you want to earn pocket money, you can download it to mobile phones or other computers to start mining.

4. Different virtual coins have different digging methods
coins with pow algorithm like bitcoin need professional miner to dig, that is to say, you need to buy miner first
as long as you hold the coin in your wallet as required, you can get extra token rewards
some dpos currencies, such as EOS, only super nodes can get rewards, but ordinary users can get rewards through pledge.

5. It's possible to dig, and no one can stop it. However, virtual currencies such as bitby have been declared illegal by the state, and prices have plummeted. As a result, fewer and fewer people are mining, and even drag down the sales performance and economic benefits of enterprises manufacturing graphics cards. It's a bit too late for you to get involved now, The chance to make a fortune is over. It's better to choose another project.

6. We have to use mining machines and computers to dig. In the past two years, e to policy reasons, we have paid more and earned less

representative of B2C mode

1. Tmall-a platform for serving people

the advantage of this mode is that its platform is large enough to sell whatever you want, provided there are no violations. The mall is responsible for maintaining the establishment of this platform, while the merchants are only responsible for their own business. They should be responsible for their own profits and losses, which has nothing to do with the mall. But no matter how your business is, you have to pay a certain venue fee

2. Jingdong Mall, an independent business selling procts, announced on April 1, 2011 that it had obtained US $1.5 billion in financing. Since then, Jingdong Mall has started to spend a lot of money to build its own logistics, spend a lot of money on advertising, and fight a price war with its competitors in the instry. These practices are very fruitful, and the market share of Jingdong is constantly increasing

in addition, it took advantage of its capital advantages to hit down its online and offline competitors, completely making Gome and Suning hot, making Suning become its own online shopping mall, Suning e-buy, and Gome built its own Gome online shopping mall and acquired Kuba to fight back against Jingdong shopping mall

8. Look at the situation. Some of them are fake. Be careful

9. Now it's gone. You have to buy dozens of graphics cards and have sufficient power supply to ensure that you don't lose money. The cost is millions. If the value of the bitcoin g is lower than the cost of electricity and hardware, you will lose money. Then there will be a wave of absenteeism and low price sales of graphics cards
finally, I wish all the miners and their families the best of luck
