Being your own bank sound very powerful, until you realize that it's not that easy, Banks have a lot of services where people help them to manage like customers service, fraud protection, backup programs and security teams.
In crypto it's a different story.
You are the bank, which means you are going to cover all these services that the banks have to hire people to manage, The. Security team, backup system, fraud prevention and customer services. Being your own bank brings freedom indeed but it requires awareness, you will be the one doing all this job.
This have many times contributed to why people lost their crypto, they just don't understand what they are up against, it's no more in the hands of your bank doing all the jobs for you, it's on you to secure your bank "Crypto Wallet" like your life depends on it,
If you want to be your own bank you need to act truly as being your own bank, take the necessary actions and arm yourself up like you are guarding your strong room. We are going into 2026, scammers won't stop finding a way to break your bank, do all you can to avoid stories that touches in 2026.
In terms of securing your crypto, it more like saving in a bank because banks do give you a debit card and a pin which you're to remember in other to claim ownership of your account the only difference is that if you forget your bank pin, you bank can possibly create another one for you but for crypto if you lost your mnemonic seed then there is no way you can recover that wallet back. So in essence you both need to keep your seed phrase and your bank card and pin safe in other to avoid scam or hackers gaining access to your money. Keeping your seed phrase safe isn't as difficult as you put it to be, provided you have a safe location(not the internet) that you can rely on, you're good to go. You can use the most basic/ traditional method of storing seed phrase which is writing on paper.
