Not going to knock it as to be honest I've never tried dash or looked into it in any detail. I'm not sure why I would ? What advantage over BCH does it have ?
instant payments ( faster than 0-conf and more secure ), it has mixing already and it has anti 51 tech... basically it has everything that BCH is building if you are honest.
Only masternodes can vote on decisions. in 2016 it took 2 weeks to decide they will raise the block limit as scaling method.However now there's shared masternodes so.
