What if i buy more ghs from cex.io?
Does it worth to ?
This has already been answered. I'm not sure what you're trying to accomplish here. You've got $15. What do you think you're going to obtain with that $15? You certainly aren't going to turn that $15 into $30, $40, $100 by mining. If BTC price skyrockets, you might make some profit if you just straight out buy BTC now and hold onto it.
Let me just put some numbers out there for you to hopefully clear this up once and for all. Right now, that $15 will get you just about 0.03
BTC. If you wanted to purchase hashing on cex.io, you would get about 10GH/s. As of this moment, that 10GH/s would expect to earn about 0.0002109
BTC (which is about $0.10) a day. Now, you have to factor in cex.io charges hefty maintenance fees, and that in about 3 days the difficulty is going to go up again and you're going to make even less. This pattern continues to repeat itself with you making less and less as time goes on.
Even if the difficulty never changed and cex.io didn't charge you any fees and you made the expected payout, it would take you about 150 days to make back your initial $15 investment.Still think you should purchase hashing power? If yes, re-read what I wrote over and over until you understand why you shouldn't.
