Hey guys the query is to know that company is selling asic and send in a time less than 30 days now and have seen that talk about 400Mhs or 600 as I imagine butterfly began to send in 2015 Grin given previous experience but the question is are can buy something still profitable? and not have to wait that long?
Most miner that is worth buying need pre-order. Check kncminer, cointerra and hashfast. They are quite reputable.
