The majority of coins that are live on coinmarketcap would disappear in 5 years, because they are suffering from lack of money, strategy and competent management. Besides, 70 percent of coins are not backed by a working product.
Lack of money is an old reason to leave from all of the responsibility of developers to the investors. This already happened since the ico trend has begun in the past.
Remember about the latest audit from some trusted parties and more than 80% of ICOs are scam icos or these icos have no competences to create products.
These scam icos have been selling the idea only even that's a nonsense idea.
