The price of Neptune is unmatched ... Cointerra , Black Arrow , XtremeMiners , AMT and HashFast not come close in quality at all . Cointerra say have a great money but deliver only in April. Black Arrow is economical and powerful delivery for investors but not in groups . XtremeMiners ( 7.5 T / s for 14k dollars ) is the most powerful on the market with a good price , but it is a very young company and many are skeptical about its existence . AMT for now ( found so far ) is what else comes close in economics and relative confidence . HashFast cost a bit more expensive than AMT .
So unfortunately yes, you would have a reduction in their quotas .
If you bought 100 shares in Neptune, the AMT you would have 80 , with the conditions described in the previous message . But the delivery would be in February ( same period of Neptune) and in this business any month unless it can be crucial.
