My last miner purchase that was actual hardware unfortunately did really poorly and never reached 100% ROI
With that being said, I've bought a few MH with GAW Miners and I'm currently at 85% bitcoin ROI and should meet > 100% ROI soon, which is a lot better than my previous hardware miner did.
That sounds like an ad to support your ad campaign signature. I'm quite sure your cloud hashing will be just as big a loss. I've described how cloud hashing works here, though the same is true about all mining:
You learn about bitcoin mining, read lots of advertisements, visit lots of flashy sites, compare prices, look at forecasts, consult experts, examine graphs, pick apart forum posts, make predictions based on all that and then you flush your money down the toilet. Then you spend the next 6 months making shit up to convince yourself and others you made money in the process.
