Yes, this is possibly getting too large too fast. Yes there is a chance this is a bubble because the barbers and shoeshine boys are talking about it. But there is also a chance that we genuinely are at the beginning of the transition from Fiat currencies to crypto (beginning of the S-curve mass adoption). And given that we live in the digital connected age dealing with a virtual concept, it takes a lot less time for things to catch on and spread like wild fire, as opposed to other transitions in history like snail mail -> Email (which also was not that slow).
And if at all that crypto vision does come true, the value of BTC and some of these other top cryptos would be worth a _lot_ more than it is right now.
Again, this could go the other way and it could all come crashing down soon and maybe the hype dies down. But I feel a majority of the HN community is just waiting for that to happen which I did not expect.
