99% of cloudmining site are not profitable.

That's all.

I think that this is an exaggeration. Profitability is determined by lots of things, e.g. the price fluctuation of the coin that you mine, when do you enter cloudmining, which company you use and what price you pay. Surely you should do your due diligence and decide which is the most profitable option!
I have also tried Zeushash, and (although this is a scrypt cloud mining service) it seems to be working very well! I am sure there will be similar options for bitcoin cloud mining.
