OK, this may seem like a stupid question, but I can't seem to find a good explanation of the difference between an SMT and the coins that other users seem to have created for their specific "tribe" (I think that is what is meant by tribes) that I've seen around, like on the bid bot pages for Steemmonsters, Sports and others. Is there a quick and easy way to differentiate an SMT from one of these custom coins, or is it just one of those things that those of us not steeped in the constantly changing vocabulary, rules, themes, attributes and nerdisms of crypto have to accept on faith that, to at least some folks, this all makes total sense? Thanks for any help.
