it's not profitable to buy at 1.45 bitcoin for 180Ghs, is it ?
with the current difficulty being 2621M , if you receive a S1 tommorow, then you earn 0.036btc/day with a 180ghs.
You never gonna reach 1.45btc due to increase in difficulty, so why buy this now ?
Exactly, you shouldn't buy the S1, rather you should get more Alcohocoins.
