Obviously bitcoin is a bubble, don't kid yourself. People should just take a step back and calm down because there is way too much emotions involved into it, nothing is rational.
The bubble get bigger and bigger because wannabe millionaire are jumping in blindly and expecting that the price will be higher tomorrow, after tomorrow and so on. People are not buying bitcoin because they believe in its capacity anymore, they just want to join the party and follow the lucky geeks who made tons of money out of bitcoin...
The myth of the giant disruption saying that bitcoin will replace fiat currencies is not realistic. The potentiel of crypto currency and blockchain in itself is undeniable but it doesn't mean that bitcoin will be a global currency integrated to the real economy at any time soon because there is too much reasons that make it impossible (economically, demographically, socially, technically, ...)

Lots of hopes, euphoria, panic, beliefs but nothing tangible to prove that bitcoin is worth the price it is.

I personnel think that the bubble is going to pop (6 months, 1 year, ...?) and the price will stabilize around 2/3k and stay there. At this time, bitcoin will be what it should be: a liquid asset and great store of value, the gold of the internet.
