How long does it take to buy Yachuang cloud mining machine

1. I bought a hard disk miner, delivery is very fast, direct remote help me debug, or more satisfied

2. It doesn't matter. First of all, I'll take photos of the bar code and N / s code of your graphics card to store evidence. Second, I'll take a complete video of the graphics card as evidence. I also need to take photos when I send it by express mail. I need to see if the buyer has real name authentication and what the sesame score is. If the credit is good, I'll deliver the goods, if not, I'll cancel the transaction,
