re: what in gad's name has happened to gpu prices over the last two months???

Nah, it was when it went from 250 up to 1200. Everyone bought in with pretty much identical profit margins to compared to two months ago. Then it floundered and profitability hit the floor, just like now. At one point I was averaging around $50 a day with two GPUs, then a month later I was making $15 a day with 6. Your logic is flawed because you're thinking about this as someone who put actual money into it, not from the miner's prospective.
