Is it better to just mine one coin, e.g. Zcash, than to constantly switch to whatever coin is the hottest at that point? I've tried autoswitching software and it doesn't seem to make much of a difference, but i didn't trust it and didn't run it for more than a day or so.
Complex question the less you know the easier it is to simply mine zec at nicehash .
The assumption for that is you have nvidia 1080 or nvidia 1080 ti.
Have the zec auto convert to btc. Don't change a thing for a week or two. This helps you see your true profit.
Once you know what zec pays if you have multi rigs you can try 1 rig on zec 1 rig on another coin.
Compare the two rigs earnings.
I have four coins maybe five I shift. But I always mine some zec at nicehash and use it' as a baseline to decide to shift or r not shift.
