Now looking at both cases, with self custody, you get control, but that control also comes with interesting responsibilities. Then comes Bank custody, you trust others with your money, but you're also getting some level of convenience.
Obviously either one works for different individuals based on individual preference. However let's not move away from what makes Bitcoin unique and different and that's the situation where banks have less of a say in holding money and the fact that we may not rely on Banks anymore.
So Banks now want to hold Bitcoin, interesting!
I wouldn't say this is a nice initiative or neither a bad one, but one question I will love to also the banks is that what measures have they put in place to ensure that users Bitcoin don't get stolen by insider employees who are working in that bank? Because the chances of an employee stealing a customers Bitcoin in this type of institution is very high. Because unlike traditional banks where each transactions are been tied to a particular individual, account, name and personal details. When it comes to Bitcoin, it's very not easy to trace the owner of a Bitcoin address of a non custodial wallet.
So submitting your wallet seed phrase to a bank, simply because you are scared of the responsibility that comes with keeping it safe,
clearly shows that you are not worthy of owning a Bitcoin. Because this is a stupid idea. It is better you just focus on keeping your money in the bank.
