IMO new season of mining is over the corner, the trade volume is much higher then the best days of 2018 when BTC was at 20K-lets see how efficient the new 7NM navi will be.
My prediction for navi is that it will be good on the nividia algos. Its not gonna beat vegas on xmr type algos. I did see somewhere that AMD said navi is not as good on compute as it will be on games
