Big company's stocks or even US dollar more look like bubble than bitcoin. They print dollars non stop and it's not backed by anything. It's impossible with bitcoin, inflation is also impossible and it's capitalization is still several times lower than some big IT companies. Moreover it's backed by public consensus by people who believe it can be a great medium of exchange in future due to btc's advantages that we all know about.
I think bubbles are synonymous with dumps on a large scale, and this happened to bitcoin after 2017, at that time a lot of negative news was circulating, so it gave an effect of fear to investors who wanted to buy it, because it fell to the range of $ 3500, but eventually bitcoin rose until we can see it today, and the sharp decline will not occur in the stock currency or forex, except for extraordinary events
