I agree. The crypto industry has made a lot of progress toward securing private keys, with another 5-10 years of cryptography I think it will be a somewhat 'solved problem', thereby allowing companies like PayPal to offer their own custodial / layer 2 services with minimal risk. Institutional-quality digital asset custody and signing was basically non-existent until Fireblocks launched just over two years ago, and there is still a lot of progress to be made on cryptography primitives and infrastructure best practices.
