When you talk of bank and Bitcoin the two are different both in nature and operation.
1: Bitcoin is a digital currency, and bank is a financial institution without the feature of currency like bitcoin.
2: bank is a government-regulated financial business, while Bitcoin is decentralized and unregulated.
The only similarity between the two is the sending of money from one person to another, but the bank is a third-party storage institution while Bitcoin is self-custody.
