If they did a survey of how many ICOs are really useful and are they to develop the world? I believe they would be less than 5%. Nowadays anyone wakes up, uses little money and creates an ICO and mind that has a great team and is going to do something X or Z and what irritates the most is the reward bounty hunters who do not care about ethics and just care with their payment at the end of ICO and the scammers have realized that.
I hope good project will have luck on succeeding and providing some values to their costumers.
Finding a good project is very difficult.
honestly, I don't know people who really make money on investments in ICO, only Bounty
this is a topic that could be debated
