Nope. I have made profitability assessments on several different cloud GPU solutions having different hardware.

As a general rule, for every 100 USD you'd only mine about ~50 USD's worth of crypto-currencies.

Which is not surprising since on these products you get a fancy motherboard + high-end Intel CPUs + boatloads of RAM.

These are of little to no use when mining, and account for about half of the cost of this hardware. Also, the local cost of electricity is not the lowest price in the world (China having one of the lowest)

While the price of hardware is fixed, crypto-currencies possess a difficulty adjustment mechanism. This makes the whole system have an upper bound on mining profitability, and this bound converges on the profitability of the best-yield-hardware's. Which would be something to the tune of this [1]. Note that while having 6 GPUs, this system has 8 GB of RAM and an Intel Celeron.

EDIT: We're talking about IO-bandwidth-bound crypto-currencies here, like all the ones based on EThash[2][3], Ethereum being one of them. Bitcoin's upper bound on profitability is set by the best ASICs for SHA256 processing.
