i wouldn't consider all crypto to be worthless even though there are lots of them that seems to appear so, this days, many ico project are trying to back their project with usable product or services which can benefit people, with such project dominating the market, providing different services to their users then such token will surely worth something with time, there are some level of difference between ico's of 2017 and now,nobody wants to invest on hype alone, now investors are very selective of what they put their money, only solid project with good fundamentals are surviving.
