Most of the new coins only have a short run until they fail; today the chance to get lucky are quite low.. I'd look for the ones with something like 500/600k cap
No! Its not like that. We should invest in new coins as well even if they are undervalued because sooner or later they are going to rock. But new coins demand patience. But if you really need money and want to make profit within short time, then its good to go with coins that have a good market value just like bitcoins.
