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.
Before you create this thread, did you forget that bitcoin is a decentralized currency? Why will you be the one to createa place where people will store their bitcoin wallets? It has been in the industry for a long time now, and no one complains about that. People have been using their wallets for 10 years now, and nothing happens unless you, as the holder, misplace your private key and another person sees it and packs your money? If not, I don't think it will be important for people to pay you so that you can create a place where they will store their bitcoin when there are wallets to do that.
However, do you think people will trust you on this? Because when it comes to bitcoin investment or any other cryptocurrency investment, high security is required, and anybody who believes I think you can get access to their investment, so that is why nobody will trust you on this. I think you should focus and do something different in the crypto space.
