I agree, crypto is great. BUT... How do you account for the fact of there being an UNLIMITED number of competing 'currencies' EVERY ONE of which claims that its value is based on there being a 'limited supply'. It doesn't add up. I wish it did. But it doesn't. In other words, this is a mania that cannot last in its present form. It's just not logical. Of course, people want to believe that what they're buying is 'limited' (and therefore worth more than air) but obviously this belief is not rational. Every one of the 'altcoins' is based on a 'good idea'. But unfortunately 'ideas' are cheap as dirt. If you don't believe it, just pay attention to Steemit for a while.
