Hey mate,

I'm sorry to hear this happened to you. These days I've been doing a lot of research on Alibaba, as well as on other websites, to find legitimate ASIC manufacturers to mine Bitcoin.

There's only a handful of them who actually make the machines (Canaan, Bitmain, Halong, Ebang, etc.) and they are large companies; everyone else is either a trader or a scammer.

I came across this very same company you mentioned, and they offered me Antminer S9s for a very cheap price. After I asked a couple of questions, they stoped replying.

You have to be a little bit inquisitive on Alibaba, ask them for their company registration certificates, pictures from their factory, have a phone conversation if needed, etc. If you do it, most scammers and even traders will just leave you alone and go for their next victim.

It may help that I've lived in China for many years and run a small sourcing company with offices there and overseas. If you need help sourcing the hardware, you can get in touch with me via pm.

Cheers and good luck
