How much did you earn? I get 1 $ in one week (100 GH/s).

Did you withdrawal any bitcoins. I want to buy some hash power, but i am not sure if they pay.

But be careful whit referral links. I get downvote from @steemcleaners because of referral links.
Now i use them like this: https://steemit.com/bitcoin/@fbslo/free-bitcoin-mining
