Agreed.This is the one of the question that newbies always drag down in the forum.Before making deposit always check about the site.If it is a cloud mining site always ask them questions regarding their mining proof.And if they are ignoring your messages and emails then it will scam later.As a investor you have right to ask where your btc is getting invetsed or where it is going.Well since most of the cloud mining are ponzis I recommend you guys to but some online has rates and point it to pool and start up provided if you have enough btc to buy minimum hash rate
