Anyway, I found my favorite investment : GHS in cex... See sig 
Sorry to hear that. I think mining will never break even in itself and the only way to earn BTC there is buy low and sell high, which is highly risky. I suggest you just put your BTC in cold storage instead.
Definitively not cex mining, but with cheap miner it is possible, sometimes you can find someone selling for good price, but rarery
