I guess I lost my train of thought in my essay but I understand what you are saying, let's do some math, GPUs run about 300$ for a good miner that hashes 25Mh/s that will produce about 4 ETH a year (baring insane difficulty increase) on genesis mining you can buy a 25MH/s contract for $750, so clearly they over charge you on hardware, but on the other hand you don't pay for electricity and you have 0 hardware downtime. So in one year a rig with one 25MH/s GPU would make you about $1139 by todays prices and difficulty. If you were to invest $750 into ETH you could buy 2.84 at $280 per ETH. and maybe the price will double but the only way you will have made any money buying ETH is if you got it at 280 and it jumps to 600 or so, now I totally think thats possible but in the same amount of time you would have been mining more ETH with genesis for the same amount of money.
