As off topic, zec has been pumping and right now is the best time to dump all the zec you trolls have for xmr or any other gpu only coin.
That's what ive been telling people today, best day to dump zec and pick up some better bags.
Remember the D3, remember the L3... bitmain flooded the market with these... they are room heaters/door stoppers today
at a limit of 50 per customer the market will soon be flooded with Z9 mini's... they will quickly be as unprofitable as a D3...
then will come the Z9 Monster with 10X hashrate of the mini - rinse and repeat....
the only coin that remains somewhat profitable with an ASIC today is bitcoin and that is only because the markets need bitcoin as the trading peg...
if bitcoin wasn't the petro-crypto... the bitcoin asics would probably also be paperweights
and remember 2 years ago, ROI on a bitcoin ASIC was what ... never???
