unfortunately what is happening right now is price going up due to lack of supply due to hoarding, not any new magnitudinal shift in utility that has come online with btc business in the last 3 weeks. look at the tx graph it has not shifted since last year.
people who got paid in btc a few years ago are sitting on thousands, some of them are not providing any value to the system especially by not circulating the btc they have. they could easily take those coins and invest them into btc businesses or people to write off their massive profits but instead they are hoarding for various reasons (I realize some people didnt declare this income the first couple years and are in a weird position...). that is not healthy.
i don't recall who it was but one of the dev's once said that there would be something like 5 (or 7?) btc bubbles. market adoption driven bubbles should happen in the first 2 and 3 stage (mass market adoption, final bubble) of market adoption. there is probably some academic studies i have read on this but i dont recall offhand
my personal opinion is that bubbles should be spaced out longer than the time period between the last 2 bubbles as it takes longer for new innovations to bring about new growth curves. the time period between the last 2 bubbles was about 21 months. it is been only 6 months and people are already expecting another bubble event...
