Bitmain has so many complains about the services that they have processed and especially the transactions they have, they Delivered items that's not complete. This issue is been around this forum especially here in service discussion and in mining, so i think Bitmain is not really safe eventually and is not trusted by this time, if i will give them Rating by Stars i will give them Only 1 since there service is not well. So OP, don't ever get fool by bitmain again.
