By your logic, might as well take the $950 and instead of buying a contract, just buy BTC directly. At current price of $101, you could get 9.4 BTC. And just like the platinum contract, if the price rises about $101, you make a profit. If it is less, you will lose money. Oh, and since you are nit-picking, I forgot to include the 10% management fee that Cloudhashing charges, so the platinum would actually earn 9.2 BTC * 0.9 = 8.28 BTC.

By buying BTC directly, it is even less work than a contract. And, you avoid the uncertainties of whether Cloudhashing would actually have the hash power ready when Sept contracts start.
