When will people learn that all ICOs are failures. The only people that score with ICOs are the dev team that in the end will have a bag of BTC and the investors will be bagholders of worthless coins.

ICOs fail because the dev teams do not understand the basic principle that in altcoin crypto 95% of investors are in it for short term profit and do not care about any long term plans. After the initial rise the price dumps and gradually goes down. Secondly, altcoin crypto is not far off from running a business. Once this second principle is understood, a coin will be successful. Most coin devs do not have the experience of running a company and do not understand principles like gearing, R&D, marketing, growth, strategy etc.
