I'm still not convinced that Byteball is a pure DAG coin, to prove my position I would need to generate a lot of transactions on Byteball network to show that in certain conditions (related to DAG topology) TPS growth is negatively impacted by necessity to pick the main chain. If you compared Ethereum (which calls itself block
chain) and Byteball you would see that they don't differ much:

If you looked at IOTA you would see this:

I'm not interested enough to make sure that my assumption is correct, but you could help by generating a lot of transactions and posting here the topology of the resulting Byteball DAG. Try 10 TPS on the testnet maybe?
