How dangerous are new projects for the real use of blockchain? We have already seen the story of the CryptoKitties, which brought down the Ethereum network. Can this happen again now? What projects can now grow in such a way that will affect the work of the network itself?
Any good project will learn from its mistakes. I think ETH devs will have learnt some lessons from the effect of Cryptokitties on the network. ETH is a very strong project, and whilst I'm sure there are plenty of bumps in the road to come, it will survive. Plus the market at the moment isn't as feverish as it was when Cryptokitties started, so I don't think it will happen again.
