Getting a cloud contract fixed on a specific coin might not always be the best thing for you, but once you have it you can't really switch (unless you can resell the contract).
We're starting MLaB that will be offering GPU's as a service. Instead of getting a resource (e.g. 10 H/s) you will be getting a dedicated GPU for a fixed price (month, quarter, year, etc). Because you have a dedicated GPU you can mine anything you want and switch between coin's if needed. This you would be a lot more flexible.Any miner from a trusted source will be allowed on the platform. You can also rent entire rigs, which also gets you the storage (for e.g. StorJ) and the CPU
We're currently extending our farm with around 160x GTX1070 cards available for hiring. Prices will depend on duration and amount of cards rented, but starting at a price of 50$ per GTX1070 a month.
