Your money is as safe as your security. I think that a lot of people are getting hacked and they are losing their crypto. This is why the bank is a safer place if you don't know what you are doing
Unfortunately, since many people don't know how to properly use and/or secure their cryptocurrency funds, they easily become victims of hacks, thefts and fraud. I believe that there needs to be proper education, to prevent such undesired situations from happening. With the use of a hardware wallet, and/or cold storage (like a Paper Wallet), you can stay safe if the specific cryptocurrency's blockchain you've invested into is alive and running.
However, in most cases, it's better to secure your money in a bank if you don't know how to do so with crypto. With banks, there's no knowledge required to secure your funds against theft, or even hacks, since they do all the work for you. Better yet, since it's a regulated entity by the government, you'll achieve peace of mind as your funds will be insured and protected in the case of loss.
Therefore, depending on your needs, you can either secure your money in a bank, or simply do so in a cryptocurrency like Bitcoin which has been alive and running for nearly 10 years now. Just my opinion
