I think mining muliple coins that you don't want, while easily more profitable, is not good for those coins as it just encourages you to dump the unwanted ones. Great idea, but not for the coins you don't want. They'll easily be dumped and another worthless coin with many worthless bagholders.

I think they are good for creating anonymous coins and once opensourced can easily be forked back into bitcoin if neccessary. Right now they aren't any good, DRK[MN(new vulnerabilities plus siphoning mining rewards)] BYTE[ringsignatures(blockchain bloat)] except for pump n dump which is fun, if you can get lucky and time it right, but good luck with that

DRK MN are already very profitable and much more economical to run than actual mining. Already the MN just collect more drk to create more MN, give them anymore rewards and you'll just be pooping on the real miners.

Might as well sell and not try and catch a falling knife. Buy back in when it starts recovering and have more when it booms again
