Hi all!
Everywhere on forum I read that mining is bad investment but from my calculations it is not:
from this calculator:
http://bitcoin.web-share.nl/said 50 GHs mines 1.2BTC per month
on cex.io 1 GHs cost 0.07BTC so 50 will cost 3.5
after 3-4 months investment should return and than is pure profit for life
where am I wrong
You assume that difficulty won't change
Once/if Cointerra, knc, Hashfast deliver their miners you won't be making that much anymore
This is a very rough estimate , on 50gh at a cost of 3500$ and a difficulty increase of 30% monthly.
