Altcoins as in those with great technology, real world applicability, adhere to current and future regulation and have proper partners?
If you mean these type of Altcoins, then yes there is a possibility for survival and adoption, for sure.
But in terms of the altcoins (s**tcoins) which have spent most of their money on marketing to get a quick spike in price but little on their tech, when regulation kicks in you can be sure that their chances of survival are very slim.
When will people learn that lots of marketing around a crypto project doesn't always mean it is a good project?
