I'll just leave the reply from Andrew here (not having wanted to start an argument):

Well it’s true that I am biased, but layer 2 is not layer 1. Koinos can also have layer 2 solutions. Hive cannot have layer 1 smart contracts. Curious, did he point to anything I said that is not true? Or is it just criticizing me?
Because that would be a logically fallacious argument known as “ad hominem.” I, for example, did not say that Blocktrades is saying what he’s saying because he’s such a large HIVE holder, I made technical claims about KOINOS.
Here’s a question no one in the Hive ecosystem seems to want to think about: If Graphene is such a great architecture, why are there so few projects using it?
In open source, it’s all about the level of adoption. The more eyeballs, more developers, more engineers working on the codebase and building business on the codebase means fewer bugs and lower costs for everyone. The fewer projects using an open source codebase the more work is on those who do and the higher risk that bugs aren’t getting caught.
