i checked this morning nicehash and multpool .
all i can say, no interest with the scrypt and sha256. the buying price of mining capacity is equal to the profitability level on multipool. It really have no interest to buy Something at 1 and resale it at 1......
but, when i checked the X11. you know the algorythm of the dash.....
look at it :
profitability is around 0.029 btc/Th(i convert it to make it fit to nicehash)
and now look at the lower buying price on nicehash:
right now the lower buying price was 0.018 btc/TH!!!
if you calculated it, the marging is more than 30%
so enjoy!!!!
