I know less than nothing about bitcoin, only the various articles I've read.
Investing is different for each person. There are many strategies, timing, believing, investigating, underground info, dubious and illicit activities, etc., etc., etc. Some get rich with insider info, with the Web, with the dot com gold rush, with the diamonds trade, with anything you name it.
Bitcoin is highly volatile and risky, it has a tough way to measure, we don't know everything, just like the tech stocks, the energy stocks, the international markets, ...
Coke is good, Apple is good, ...
Tesla? It goes against some numbers.
Amazon? Warren regrets not having bought earlier.
Bitcoin is for people ready to lose their money. I personally wouldn't recommend for normal investors. But for heavy gamblers yes, who have extra money to lose yes, or risk to gain in a computerised world.
And I don't trust banks.
