Crypto world did their best to assure people's comfortability and provide what people wanted to know about them. They provided the easy and fast transactions, it solves a lot of the problems which are connected to centralized nature of assets/currencies, but all of the businesses are not perfect so we can really assure that something missing in every side of it. Like the scability, not just the crypto world has the problem about that. So for me, crypto world has no missing service but it has a limitation that others too encountered for I believe that Only the imagination has no limitation.
