Even today they still call it a bubble every time when Bitcoin started to decline the market price and drop so big. They just compare it to the Tulip mania because of the sudden fluctuation of the price of a single Tulip before and then later on it's just gone which brings to most investors to get bankrupt when they bought the Tulip for a high price.
Its true, many peoples seem happy when bitcoin price drop and they keep saying buble are burst. They dont looking on bitcoin price history and if they looking on it, i am believe they will not saying bitcoin is buble and maybe they will investing their money on bitcoin
i am agree with you, they did not see the bitcoin price before its jumping to around $20k.since the begining bitcoin price has high volatility , but finally its able to reach new high.
