I think that picture isn't relevant in this situation, and it doesn't demonstrate the situation being discussed in the OP, because the picture you posted basically shows that Bitcoin is available 24/7 while banks get closed and also aren't operational on weekends, but I basically don't understand why this comparison has to happen because just like Bitcoin, banking transactions are possible even when the banks are closed. Only because the bank is closed it doesn't mean you can't make transactions as long as you have internet banking or mobile banking options.
Talking about the issue being discussed in the OP, I think it has always been necessary for people to do some research before getting involved in Bitcoin and at least know the difference between custodial and non-custodial wallets so that they don't use centralized services for holding their balances even after joining a decentralized market. It doesn't make any sense to let a third-party manage your assets when you can literally do it yourself an stay out of any sort of threats or anything where you account could get blocked or frozen, and funds confiscated.
You are right, the picture looks good and is positive in relation to Bitcoin. You can also carry out transactions at the weekend with a bank, but not everything. For example, international transfers dont work within a few minutes. Or, in some cases, larger amounts are not transferred abroad without verification. This is not the case in all transaktions, but it is not 100% possible. Cash withdrawals are also not possible on weekends, or larger amounts of cash must be registered, sometimes two days in advance.
Only bank branches are closed on weekends, while online banking is open 24/7. I think you understand that because you are also using banks for your daily life. You are even using it more than bitcoin because it is still the main means of payment.
Like everyday bills, or on the weekend when you take the kids out, do you pay with bank or Bitcoin?
In all fairness, banking is not perfect, it has its own drawbacks and risks. We should not put all our trust in them and let them hold most of our money, not only because we do not have full control over our assets, but also because inflation will erode their value. But there is no denying that we still need it in our lives.
Thats true, we still need banks. They control money, which isnt the best way, but they also protect it. Or protect owners that they dont lose it. If you ignore the financial crisis of 2008-2009, when many people lost their money. But we need their services and they keep the economy running.
