Hi all
Pretty much a newb here, mined a few years ago on my pc but gave up after a few days.
I'm looking at coinfirma.com here, apparently they claim to be the cheapest or something, can anyone tell me in laymans terms what 10GH/s on a 1 year contract is likely to make me, or lose I assume. At €100 I'm thinking of giving it a shot so I can get my head around the whole thing.
When I type 10GH/s into a bitcoin calculator it gives me this

According to that I'll get my ROI in about 7 months & the rest is gravy? Is that true or am I missing something obvious here, I mean, what's the catch??? Why aren't they using those machines to mine themselves, I'm confused.
Can anyone shed any light on my thinking?
Thanks
