Do you really think they would deliver your ASIC or give you a small amount back?
I wouldn't bet on it. De facto: 50BTC did their business with stealing users money. It's a huge scam they did.
But it seems that this is their business, to scam people.
So long
It's my friend's order so I am not the one who is worried

Anyway, 50BTC is nothing to do with the whole Bitmine situation - they've sent the money.
The only reason I am asking it here is because 50BTC was (is?) the shop that sold my friend this device. Guess I'll write to support
