Instead of investing those I think the best thing to do is to buy your own rig rather than placing our money in cloudmining site since it has bad review and also its so clear that they have run as ponzi scheme right now thats why we should need to avoid this one and try to find other option where we can earn more profits.
I must however point out that mining is a done industry for the average person. It's simply not worth to buy yourself a piece of hardware as investment.
If you are looking to make profit, either get involved in trading, or just buy and hodl Bitcoin for the long term ~ buying Bitcoin always beaten mining in terms of profitability.
