There are many great features of Obyte and the one downside I could come up with has already been solved.
It is a well-established Distributed Ledger system of 4 years and has many developers working on it. There are always new and innovative features coming up. These features really increase the real-life use cases for Obyte.
I think it has a great potential and I think everyone should, at least take a look at what they have done and are currently working on. See full review
