Feel free to share your guess, but please back it up.
Does surviving or not depend on the amount of demand?
Or does it depend on the quality of the tech behind the project? Those 2 don't necessarily go hand in hand.
It seems to me that BTC and Ethereum thank their growth prospects to their established names, rather than the tech behind it.
If you think it's different, let me know.
Personally since the number of altcoins in this market is so huge it would make more sense and be way faster as well to talk about the altcoins which have the greater chances of surviving, as the majority of the coins that are now in the market will at some point collapse during the next two years as investors are not willing to risk their money with them anymore, due to the adverse conditions we are going through in the market of cryptocurrencies.
