So, the puzzles keep getting harder as there are less and less to be mined. Interesting. Bitcoin value - scarcity and increasing difficulty. Good one.
I absolutely agree with you, it's unthinkable! I've mined a few, but when I sell for Waves on the DEX, iQCash is not worth much at the moment. I guess now is a good time for mine and hodl, but I'll probably wait till it's worth more.
You should get it on more exchanges. I know Waves DEX has improved a lot, but I prefer the Binance and Bitfinex.
