Just a word of warning, in the last couple of weeks a number of websites popped up, promising huge returns, like 0.20% per hour, meaning ~5% a day. Both for depositing your Bitcoins or for investing in mining pools.
These are all Ponzi scams! All of them! Lasting perhaps 1...2 months, if not shorter. As soon as newcomers dry out they will cash in and run, and all your money is gone.
Characteristics of those:
- similar template based websites
- fake company registration paper (PDF) from UK with a fake virtual office address
- a track of small Satoshi payouts as proof that it would work
- website registered in the Carribean with anonymized data
So ask yourself, if you would give those scammers a single Satoshi or better show them your middle finger!
