So I don't recall how far you got into the profitability calculator stuff but without knowing what your daily maintenance fees where or any other daily fees you were incurring it's hard to help. If you have your contract pointed to a PPS pool (if given the option) then your earnings dropping by 10% doesn't make sense. Here is a reply I gave somewhere else to round out my impressions of cloud mining.

I mine, so I have a pretty good handle on how to be profitable doing so. If you can't profit by either mining at home or having your miners hosted you are better off buying coins. Hosting is different from cloudmining because you own the gear, your just paying them because they have lower electrical rates to offer.

Cloud mining, you are essentially paying off somone else's gear for them. The contracts are weighted in favor of the provider and allows for them to terminate early without refund if profitable. You can sometimes find a way to make a slight profit through cloud mining if they are offering a discount or promo price at the time you go to purchase, but these are still risky and not guaranteed.

The last one I saw someone post positive earnings for was Bitdeer.

As I noticed if the price going up then my daly payout is decreasing.
This seems to me a logical solution.
What do you think?

Not to mix trading and cloud mining. The price in USD shouldn't directly affect your daily payout in BTC, until price pushes up the network hashrate which pushes the Diff up.
