If people were looking at something safe I am pretty sure they wouldn't put all of their money into some "code". I know that there is much more to bitcoin and all of crypto then just being a code, but the reality is that we are literally talking about trusting more to Satoshi's code then we trust government backed banks. That should tell you enough about how little we trust banks, the whole reason why bitcoin even has any value is because banks and fiat monetary world we live in is discouraging for people who are not wealthy already.
Definitely, you may not become as rich as Elon Musk, but all of the people who are at the for best top list right now are people who had families with money. Crypto gives people who came from nothing to have a chance, and that is why we are putting so much trust into it. Is it risky? Yes of course it is but it is surely much more equal in risk to everyone.
Could be a "code" in its core but people are not investing into that code, they are investing into an idea that supports that code. Bitcoin is a currency that is as far away from governments and banks as possible. This is why we invest and use it because at the very least people know that they are actually investing into something that can't be meddled with for the benefit of some people.
Corrupted nations consider it as the greatest thing ever, in corrupted nations many powerful people do whatever they can to make as much profit as they can which results with citizens getting poorer and poorer whereas rich people keep getting richer. Maybe someone from UK could not understand the value of the idea behind crypto, which I am sure some do, but there are whole nations who understand the benefits of bitcoin and what it stands for.
