Do you guys really think this "could be the one"? I don't want to sound pessimistic, but every miner I've purchased has yet to break even. I'm about to unplug my A3 and sell it on eBay for $200. I bought a D9, mined for a week, and then flipped it on eBay. I ran the numbers through mycryptobuddy, and maybe, possibly, this thing could turn a profit.
