Has anyone tried
HashFlare ?
I want to know if i should invest in it...
Legit or not, it's not profitable to invest on cloudmining sites today. You have to purchase tons of hashpower and that will cost you a lot. Plus the fees which your earnings there can't be covered. If you think
BTC1 investment in that kind of system is profitable in the long then you are wrong. Return of investment is horrible and after reaching that phase, it's not worth the time you spend.
Better find another way to earn bitcoin. I will disregard the scam thing but Cloudmining is not welcome anymore in the community due to mining difficulty and rewards.
