Green light of ant miner doesn't work

1. Now mining is not popular, and the related services are also very perfect. There are many domestic repair shops. Go to today's miner website to find them, or ask them to recommend some reliable ones close to you. Now the repair price is not expensive. If you don't want to repair them, you can sell them directly

2. Ant miner efficiency, that is to say, this thing can't work, can't use, don't support.

bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

unlike all 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

extended data:

bitcoin is the first distributed virtual currency. The whole network is composed of users and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom. Bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

bitcoin requires a private key to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself. Bitcoin can be remitted free of charge, but in the end, a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster execution of the transaction

As a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay. Users can explore the computing power of different hardware on many platforms

5. Ant S7 traffic lights are not on, should be the problem of low voltage or poor heat dissipation. Suggest to go, you can go to the official to ask, technical personnel will let you know. It's not a problem.

8. Exit light is to remind people of the exit path, direction, especially when the light is not enough. It can be seen that it is always on in all kinds of public places, and the switch can not be set
emergency evacuation lights are used to prompt people to evacuate quickly under special circumstances. They are only turned on in recent emergency situations, and the switch should be set
