been mining for about a year, but will have to say this is the absolute worst time to start mining in my opinion.
asics are attacking all algos, fpga is on the horizon, and new gpus are scheduled to be released by eoy. Even gpu's are still slightly overpriced. There's absolutely no reason to start a GPU mining farm.
Even starting an ASIC farm is questionable and FPGA are so unproven at this point, the risk is extremely high.
Don't forget to add to that equation = Ethereum is starting to transition from POW to POS.
Basically when POS hits, the profit of all other mineable coins will severely decrease. This has been explained far too many times already. People are dumping GPUs while they can. People who don't do enough research are still buying them. lol.
