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.
The faith in banking systems only exists because of the illusion that government can provide the best financial security to its citizens. It's an appeasing illusion, because any financial troubles can then be blamed on a 3rd party instead of the individual holding the funds. I'd argue Satoshi's code isn't merely an arbitrary string of numbers but an entire philosophy of decentralization. People trust banks a lot, and will do so for a long time until they're forced to recognize that the government does not have any single individual in its best interest.
