I am interested as a growing Crypto investor and enthusiast in the idea of having all my coin stock in one place and being able to do risk management at a glass through the basket analysis part of the project.

How would we know that the vault is safe and secure and cannot be hacked or stolen as we are then putting our coins in the hands of a 'third party' as it were.  Just asking a question any random outside investor would ask. I know I can see it like a portfolio asset management service on steroids that has more liquidity and can be transferred to others also, but to put this revolutionary idea in front of Joe Bloggs, I need some comfort in knowing all my funds are ultra safe. 

BTW I do love the ideas outlined above and if you Guys can pull it off, this could grow the coinmanrketcap at least a few times bigger and allow more ordinary folks to partake in the new coin boom
