Any coins and tokens can survive. The main thing that they would carry a certain decision. Or payment or smart contracts or something else. And of course the goal was not to raise money but to really solve some problems.
That's true. Any coin can survive nowadays, given the huge interest there is from people in the real world into acquiring them for short-term profits. But, for a coin to survive, it would need to have a solid foundation to deliver real uses in our world. Development, features, and long-term vision for any specific cryptocurrency, will help the project survive for quite a long time. When a coin stops delivering real uses to the people, then it would be doomed for sure.
I've seen many developers raise money for a new cryptocurrency project, just to abandon it in a couple of days, months, or sometimes even years. Since most coins on the market are simply copies of other coins with no real innovation, they're highly likely to fail in the future. Therefore, I think that usually the coins in the top 20 marketcap rankings will survive in the future no matter what, because they have a lot of money invested into them.
