I sent them this after I ordered an S9 in the latest batch
I would like to complete this purchase however before I wire any money I found this topic on Bitcoin talk
https://bitcointalk.org/index.php?topic=2062789.new#newThe poster said he wired the money but you have yet to confirm it. Before I wire funds I'd like to be sure there are not going to be any problems if I wire funds
I've waited over 4 weeks now. In the support forums for Bitmain, there are many people with similar problem. Some have waited over six weeks, still no confirmation.
My brother bought some miners with bitcoin though, they confirmed his payment in 12 minutes.
Don't pay with wire transfer. Not sure if you should buy from Bitmain at all, I think they're up to something. Maybe they sell all of current design just before releasing new better miner? Be careful, good luck.
