What are your thoughts on claims that the Ethereum network isn't sustainable and that it's smart contracts will be overtaken by networks like the Tron Network, Cardano, EOS? Surely Ethereum 2.0 should help?
I don't think any of the projects you mentioned can take Ethereum's place not even EOS. Ethereum's commuity is very big and despite all the problems, more than 90% of ICOs are still on Ethereum network.
