I would invest in NEO for two reasons,firstly Neo is more advanced in terms of code. Secondly, Neo will not be charging extortionate fees in the future, as the founder of Ethereum plans to action.
I have to buy any new Cryptocurrency with Ethereum and sometimes the fees cost me more than Bitcoin fees to transfer!
Neo is a solid cryptocurrency that is Chinas national crypto and is an infastructure crypto, so new cryptocurrencies can be based off the advancements of NEO!
