So instead of compromising your own bank and investment, why not settle for the less stressful and less risky, yet you still gain the same convenience you desire.
Compromisation and exploitation come from other entities, not by yourself but you can set up more convenient conditions for attackers to compromise/ exploit your accounts and your fund in banks.
However, everyone has different mindset when it comes to this matter. Some just love to take a more challenging and more risky task, and navigating bitcoin as our own bank is a perfect example. But one will only succeed if he is always ready to learn and explore things, and do things with high caution. If you are not this kind of person, I won't be surprised if you stick to banks and let them managed your funds.
Bitcoin existence gives us very good option to have our own banks, own bitcoin banks, and have full control of our banks. It's worth to note the importance of our practice decides whether we actually own and control bitcoins or we just have something like bank accounts. If we use non custodial wallets to store our bitcoins, with private keys, we truly own bitcoins and control them, it's different and better than banks.
In contrast, if we are either unknowlegeable, lazy and careless, we use centralized exchanges, exchange accounts, custodial wallets for storing our bitcoins, we lose our bitcoin at that time, and we will never have control of our bitcoins before we submit a withdrawal request for sending our bitcoins from these platforms to our Bitcoin non custodial wallets.
Reminder: do not keep your money in online accounts.Exchanges are very scam.
Cryptocurrency exchange graveyard.
