For me, both are not safe, anyone who plays on the internet definitely has risks, one of which is hackers, banks are prone to hackers, crypto is the same, whatever the name of the place where crypto assets are stored, for me the safest investment is gold, you have nothing to do with the internet and you don't need to worry about hacking.

Talking about buying shares and investing, for me there are two understandings for that.
1. Bank shares, if you do this the benefits are clear, it's just that you need to sign a contractual agreement and the bank is more trusted, because if there is a problem with the customer, it is clear where to complain and most banks are responsible for the customer's funds, whatever happens.
2. Crypto as most people know, in carrying out investment activities, users do not yet clearly know what other benefits there are if they choose the wrong type of crypto investment and if there is a problem, everything is resolved, there is no place for complaints, not the same as banks.

So, both places have risks, if you talk about economics/money, the choice is up to each individual.
