To me, "early post pubescent stage of crypto" is way off; more like it is embryonic! Ask 50 people if they ever heard of Bitcoin, the grocer, drug store clerk, cab driver, cousins,etc. and see if anyone ever heard of it . Then subtract the ones who really didn't but did not want to sound dumb. I've done it and am amazed at how un-mainstream cryptocurrency really is. And we are not talking the more obscure altcoins either, but Bitcoin the leader.
I'm really excited too! Spend most of my time at it. It is already a vast world where no-one knows it all. The trick, as I see it, will be to find your niche in the cryptocurrency ecosphere and mine it (pun intended) to your advantage.
