Very true. I'm sure many of the coins/blockchain technologies of today will evolve - some won't exist - there will be bumps and bangs and pops - the 'early adopters' will most likely gain more than they lose ...it's an exciting time - and I can't deny I gloat a bit when the friends I'd tried to discuss BTC with "way back" in 2012/2013 - as their eyes glazed over -call me up for advice now lol. (I know a little bit...they think I know a lot just because I know words beyond 'bitcoin' - I get my ego infusions where I can, don't judge ;-P)
I wish the nay-sayers would find something else besides "tulips" or "ponzi" to say. Emerging markets is the best description I've heard in a long time!
