To be honest, saving money in a bank has its advantages and disadvantages and there is no absolute guarantee that customer assets will not be lost or stolen. . however, if it's just saving money, then I might prefer a bank because it's easier. if it's about investment, then I will choose crypto.
Nothing is perfect, but banks are still the best for storage. As long as we don't make mistakes that we may sometimes not be aware of, because of technological developments, crimes are increasingly widespread, but if we continue to do it in the traditional way, it will definitely be safe. It's true that investing in banks and investing in crypto always have advantages and disadvantages. Bank interest is not profitable, unlike crypto, which is very profitable. But the profitable or big profits in crypto will always be worth the risks that can occur. So always make updates and keep learning about all the things that might happen either in the bank or in crypto.
Banks always provide safety and security so it's a good choice to store our funds but if we seek profit, of course, crypto will be the best option.
However, if you store your funds in banks, you should comply with their regulations and policies. In crypto, we could freely transact with anonymity and that's what we couldn't find in banks.
There are really differences yet they both have negative and positive effects. Choosing will only depend on our personal preference and reason for saving. If it's for profit then go for crypto but if you see assurance, then choose banks.
