@riseofth it's not just BCN, other CryptoNight coins like DigitalNote XDN have been crippled by those X3 miners since the PoW7 hardfork.
Also, most ASICs and bots are still mining Monero Original XMO making the X3 still efficient mining for a small profit.
As for Monero XMR difficulty has fallen consistently since the XMV snapshot. Since then Monero is at it's lowest XMR Mining Difficulty since November 2017 (Monero Difficulty Watch) and that's a hard fact to ignore.
