My idea would be to create a bank to safely store people's bitcoin and other crypto for people who just want to hold for a lot of time.
They would register with the passport or ID, it would cost 100 GBP + 1% to deposit and verify people's identities.
Then, to withdraw, it would take 3 months, they would have to show the passport and have a meeting via zoom once a month during 3 months stating they would want to withdraw, it would cost 300 USD plus 1% of the value.
It would compensate for people who want to hold for a lot of time without having security concerns.
LOL, your idea is completely contradictory to the concept of bitcoin. if there is a bank like you think it will change decentralization to centralization. not to mention, by you creating it, it forces bitcoin owners to put their bitcoin seed or private key into the bank you want to create.
I don't think it will work and no one will want to use your service. no matter how cheap it is. After all, everyone has their own way of securing their wallet.
What's more, they still have to wait 3 months to just withdraw the Bitcoin they have.
