i earn less than i must earn from my hashing speed at these pool why:
?
In order to profit at cex.io, you'd have to increase your GHs share balance faster than the pool speed growth (approx. 2%-3% per day)
Using only your BTC output from your owned cloud mining GHs (even with reinvesting NMC), you already found out that it's impossible, the income balance is tilted against you by GHs price design there (even after the latest drop).
Must be said, however, that this would be difficult at any pool (with own purchased hardware), IMHO it would work only with very expensive and profitable gear - and every hardware regeneration cycle carries risks of getting them running in time.
For the small budget BTC miner, mining seems always associated with a loss - you can only control the degree of the loss (unless you luckily manage to sell into another EBay Block Erupter frenzy).
You're better off purchasing BTC directly (I know, less fun, but that's the only chance to be profitable unless you nose-dive into high-performance xxxxx$ hardware and take your chances)
