Yes I think Altcoin will survive or may be able to rule the world of crypto in the future, there is no reason to worry. but you can consider it when you are able to continue searching for potentially increasing altcoin in the following months or weeks. the industry is still very promising so take advantage of opportunities that exist.
each altcoin project has a unique and heterogeneous concept idea, they have a concept with a competent developer so many are finally saved after a lot of research activity on the trading market. as long as trading volume is well maintained then there is no reason to worry about it.
