My brother is into hosted mining and from what I have heard he has been making a decent amount of profit. We don't talk anymore so I have no idea where he gets it done from..
Well, why not just ask him then? At least you have someone with experience to learn more directly. But always be cautious because the risk is always there. Sometimes a scam service gives you a "decent" profit for a few months, then asks for another deposit later, and then ditches you.
