If Bitcoin is king of cryprocurrency, then Ethereum is the king of all ICOs ,do you agree? Stella,neo and no other blockchain has hosted ICO than Ethereum.
It is definitely true that Ethereum is a king of ICOs. I think more about 90% of all ICOs are being launched on it's platform. There are a lot of projects initially based on Ethereum which moved to their own blockchain afterwards. Some projects use NEO, NEM or Waves, but these are single projects which are usually not very popular.
