Absolutely erroneous opinion, how an investor will understand a good ICO or not? There will always be a concept when someone wants to take your money away from you. So scam will live and the cryptocurrency world is no exception. All the more so raw and with no clear structure. As soon as the companies conduct absolutely transparent actions and implement the DPOS or analogies, then it is possible to minimize the number of scam projects.
Well, now the regulators are very seriously watching on ICO. Now the chance to loose your money becomes less than in 2017, but of course it is very high. Everything will change in the future.
I think so too. The period of the "wild" ICO ends, we will soon have to enter the stage of gradual regulation of the activities of the ICO and this will most likely be provided by the regulatory authorities of various states. Therefore, I hope that next year the popularity of ICO will grow and this activity will get rid of almost continuous fraud.
