whenever we see an important growth in the markets those that are always looking for an excuse to not recommend bitcoin to the people say that this is a bubble, but do we know of any bubble that has lasted as long as bitcoin has lasted and that it has grown so much during the same period? The growth we are seeing is not the result of a bubble but a growth that comes from adoption, but obviously bankers are never going to recognize this as it plays against them.
It is not even the period that it lasted, it is the idea that it supports. I understand that "tulip" bubble made no sense, why they believed a flower should worth that much is beyond me, hell they still care about tulips a lot over there in Netherlands for some weird reason.
Mortgage bubble was literally people who are getting houses with the money they do not have, and remortgage their own houses that they literally own so that they could buy other stuff and so forth, basically it was obvious from start that banks literally gave loans to people that can't pay it back, I could go on, most bubbles do not make any sense at all. Whereas in bitcoin (can't say for every single crypto) we have something that is a currency, a currency that allows people to literally do whatever they want with it, and it is valued high because it is fair and decentralized.
