Dash is going to be great with upcoming version. Axe is still very cheap and easy to mine. Pivx dev left the project so its unlikely theres going to be anything new besides light updates (and how long they would last). the rest has empty or no source code available. there were couple more i think but they didn't survive this summer i guess
Is running a master node really profitable?
I am doubtful as there are many devs that left their project hanging on the air.
Depends on coin. Most of super high ROI MN coins will just get value devaluted because of high infaltion. Same as with high PoS. You you should look for decent project that has not too high/not too low payouts. So you can pay your VPS server costs from MN income.
As AXE dev here chipped in with advice, I can recomened AXE as a good project. It's still easy to mine AXE, at least for now. Sadly it's not on any of larger exchanges so buying it will be harder. Only at freiexchange.com.
true. there was so many projects with just very bad balancing, like 90% masternode rewards - with such numbers hash rate would be abandoned due simple math. masternodes got this bad reputation during winter '17 because it was a better instrument for scammers - you have additional ROI vector that would look better than any standard pow system. and it was understandable for people just blindly selling everything to get a couple masternodes - no time to read github, price is going up by minutes
