I agree that not every blockchain project has a bright future, because the topic of cryptocurrencies has not yet fully discovered itself.
At the moment, I would say that almost every project that appears new fails, what can we say about a good future. After ICO, prices fall off very low, because of this, no one wants to invest in a project on ICO, and as a result, a lot of projects turn out to be scam projects, which greatly undermines confidence in ICO and crypto currencies in general.
