Let's assume that you are giving this advice in good faith because you are not aware that cloud mining is in most cases a simple scam, and if that is not the case ROI is very questionable or rather difficult to reach when it comes to larger investments. Mining (at least as far as BTC is concerned) is profitable only for big players who can invest tens or hundreds of millions in such ventures, have access to cheap electricity and a bit of luck when it comes to the price of BTC.

If you are going in that direction thinking that you will generate some profit I advise you not to waste your money and time, much less to advise others to do the same.
