What I'm thinking of Is, a registered company specialized at storing wallets and private keys files along with KYC policy and some security protocols. would It be a profitable idea? If no what do you suggest.
Sorry, but I think this is an entirely awful idea:
Why would people willfully want to subject to braindead KYC/AML surveillance measures?
Why would people want to trust you to keep their
private keys secure?
What you are suggesting is the exact opposite of what Bitcoin stands for. Bitcoin is about the individual freedom of having the power to manage one's own money. What you are suggesting as a newcomer is exactly the same thing that banks and paypal does today: Forcing nanny policy on their users, restricting their financial freedom while exploiting and sharing their private information as they see fit.
No thanks!
ya.ya.yo!
