Of course, I agree that Bitcoin is the king of cryptocurrencies, and Ethereum is the king of ICO. Most projects create their projects on the basis of the ETH smart-contract. I personally find it very convenient, since you can use a convenient MEW or MetaMask! Recently I ran into a project based on NEM. The team constantly postpones the listing of tokens to the stock exchange, since the wallet synchronizes with the stock exchange for a long time ... I dont know how true that is.
