hashrate drop after devfee session on MTP algo, can you check?
Same happend to me, I was mining around 14.4 Mh/s, after de devfee kicked it went down to 13.1 Mh/s and didn't come back up to the 14s
You'll still be better off with TT-miner for MTP.
TrailingStop's done a good job on that algo, and I doubt you'll see any improvement using CryptoDredge.
