I like the fact that you can store your information on a public chain instead of having to put it on their servers. You also don't have full control over who has access to what. The system is very complicated, and there are multiple ways that you can block someone from accessing your information. There's also no easy way to remove an entire document from the system. Try it out for free! It's worth it, trust me. We use this system so that our clients can check if we're doing business with them or not. It keeps all of our data centralized, which makes it easier to retrieve when needed. We've saved some money by not having to pay $10 per month for each client.
