This statement is so mean and is actually racist, you are saying that every successful seller in China is a scammer/liar, which is not the case.

Of course, the majority of those sellers are not honest, but it isn't half as bad as you show it.

The problem with these mining gear sellers on Alibaba and Aliexpress is that most of them do NOT own any mining gears, they will either 'dropship' or buy the miner for you and reship it, some don't even know how to troubleshoot those gears before sending them out, and given that mining gears have a very high failure rate, there is always a good chance you end up with a broken miner.

Those "honest" seller will offer a refund if you return the miner, but well, you will lose a good portion of your money if something like that happens, I have done some deals on Aliexpress, some went well, most were terrible, and I would advise against buying used mining gears from both Alibaba and Aliexpress.
