wire transfer only was disappointing. was hoping to buy with BTC. kinda shows a lack of faith in there product that they wont accept it as payment.
Its not a lack of faith in their product, its the fact that their government has made it very difficult to exchange BTC to fiat. Same reason Bitmain seems to have moved to Bitcoin Cash only.
That's probably not the only reason behind them moving to Cash. Considering they were also one of the main proponents of the fork in the first place they probably want to keep their political experiment alive at least until S2X launches. Without Bitmain accepting BCH it'd be dead.
