If you want to cover its attributes and future potential-like things then do something rather than this because Banks have nothing similar to Bitcoin, they are shady and centralized. They need KYC if they want to access all the financial services the Bitcoin all you need is a paper wallet and an internet connection rest to the things you know. As a Bddy above said "Be your Bank", follow it.
I think they're pointing out the idea that Bitcoin is hard money, and basically you cannot just create more Bitcoin out of thin air, which is what banks do these days.
In that regards, Bitcoin cannot be a bank, in the modern sense. Because you can't just loan it to someone else and add more Bitcoin from thin air to yourself.
