Bitmain says "sold out" But on Alibaba they say its in stock. Is it real? Has anyone every ordered from alibaba?
Probably not. Anyone can open a listing on Alibaba AFAIK, for anything they want. I wouldn't buy from there. Imo; it's just going to be a hassle, perhaps you get a product, but it might not be new, or working as intended, and then what? It's not like you're going to be able to send it back.
plus the fact that if they're actually real, they wouldn't be selling them on Alibabi without a huge mark up rate. Thus it'd probably be smarter to wait for official resellers/bitmain to release a new batch, both risk-wise and money-wise.
I mean looking at the feedback,
https://www.alibaba.com/product-detail/Trade-assurance-40-7ksol-s-1150W_60787014391.html this one could be real, but is it really worth the risk? What if there's something wrong with it? I doubt there's any warranty at all on this machine.
