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 other than Ethereum.
in this point of view no one can deny this reality; Ethereum has hosted the most ICO then other blockchain.
But Ethereum gave a lot of incompetent people the opportunity to be actor in the blockchain technology and opened a big door for scammers to collect huge amounts of money with more than 80% of ICO that ended up by scamming investor.
Vitalik Buterin's project was one of the best but the ingorant made it a fail.
