By disappearing they ment to say that they will eventually fail or leave the market because they need supporters, network effect and so on. There is a high probability to see them fade day by day, but not instantly. Even though, personally I think that will do only good for the market just to keep our attention focused on the projects that really deserve it.
A project that will survive over time and will be in the 5% successfull ones will be #Blocnation. What makes me very confident about their project is that they have a real product that has been working for two years now. Check out here: https://blocnation.io/. I just love the concept of paying with tokens for real things using only a bracelet. That is one of the first steps to get mass adoption of the crypto currencies as the first mean of payment.
What's your opinion on it?
