Personally, i don’t feel 100% secured to keep my money in the banks because you know bank also can be bankrupt, so that i can't believe it. Even i faced some issues in my country banks, i can't cash my money on time. But i think there are no 100% safe way to keep money in online or offline.
Well, as long as the bank is a national bank, I think they will compensate you for the losses you have when you deposit money there, because it is a bank managed by the government, and also has clear regulations.
If we compare security between banks and wallets, then banks have better security, and it's clear how you can find reports and those who are responsible for the assets you have. I once had a friend who lost his money in a bank, when they reported it, within 1 week, the money was back intact. However, if we talk about the advantages of investing, then crypto is far superior. however, I still feel that crypto is not a place to store the money we have. I still feel and use crypto as an investment and payment alternative on the internet. however, when it comes to saving money, I lean more towards banks or gold.
