Of course crypto is cleary in a buble (as you've said and continue to say) and even in short term the price isn't very stable; but the tech still has some value > 0

Things like Steemit are one of the reasons I haven't tottaly given up.
The fact that something without a inherit value can have pecived value can bring a lot of attention and interest to a topic wich would otherwise be ignored. And greed is the engine on whice all of these values are mesh together and thrown in as fuel;

Just like politic interests gave us things like space travel or atomic science,
Greed, speculation and in-it-for-the-tech guys can give us things like Steemit (and, of course, CryptoKitties)
