But Bitcoin has never seen an economic crises as well. The following creases seems to be deeper than the 2008 one because the boom accumulation has been much greater than in the previous time (before 2008). The bigger boom - the bigger room (for crisis).
I agree with you on this, Bitcoin was created after the great crisis of 2008 and fortunately, since then until now. Our economy has never experienced a crisis on such a large scale, and we still don't know how bitcoin would react if it did. That is why I disagree with those who say bitcoin is a safe haven.
But as for bitcoin going below $10k before hitting $1 million, I think that is very unlikely and depends. If in the next few decades, bitcoin escapes the label of a speculative asset and is recognized by the world as digital gold, and they use it as an alternative. If there is a major crisis, its price will even increase along with gold instead of being dumped. But the opposite will happen, it will be dumped severely if bitcoin remains a speculative asset and a major crisis occurs.
