I think the situation is very different between ico 2017 and 2018, ico 2017 is more interested in dealing with ico so many ico are successful, 2018 on the contrary, more and more ico investors are reduced so many ico are failing or scam
Before comparing with ICO project with 2017 to 2018 at first we need to know about the successful ICO project. In the middle of 2017 there were several successful ICO project and the earlier of 2018 there are also had some successful ICO project. But i think 2018 had numerous ICO project.
I think ico 2017 and 2018 are the same, which only distinguishes market conditions. 2017 have a lot of successful ico projects, while 2018 the influence of the crypto market is not very good, it has an effect on the current ico project.
I'd agree with this only if by "successful" you guys consider those ICOs successful in raising ETH or BTC, and not necessarily those that have successful projects.
Otherwise I'd disagree. I think projects that are still alive and started in bear market are much less likely to be scammy, and their teams probably have ideas on how to make the project profitable.
