This is the kind of mentality that allows ponzis to thrive. If you want to try cloud mining, either accept that you're playing a part in a ponzi scheme and take your profits before the whole thing falls apart or choose a legitimate service and lose any hope of making a profit at all. That's the reason why CEX.IO was so overpriced. Unlike most of its competitors, it was a legitimate mining firm backed by actual hashpower. And because of this, nobody who sat on their miners actually made a profit from buying CEX.IO mining contracts except for those who bought them just before the November 2013 bubble.
Purchasing cloud mining is no different than buying a physical miner in that regard. You don't buy an obsolete, power hungry miner for above value and expect to make a profit either.
At least with physical miners, it's possible to make a profit. People have made profits when they did their own research and the company delivered the hardware on time. It's rare but it happens. Trading aside, literally nobody has made a profit with CEX.IO in BTC terms. Their contracts have been unprofitable from the very beginning. And the only cloud mining sites that were profitable so far eventually turned out to be ponzis.
