I also think so, but every crypto has its own function. It's a lot to say that the fore only Bitcoins survive this because Bitcoin is the King of crypto. But another altcoin I think there is also like Ethereum that works as a virtual machine that can run a peer-to-peer smart contract with a cryptographic cryptocurrency ether (ETH).
Yeah every coins has it's pros and cons and we cannot all altcoin will be delisting on exchanges, as long as the coin has it's demand and the community still support the coin and also the team of the coins always developing it, i'm sure it will last long in the market except a coin that has not clear background and the daily volume is under 10k USD
Agree, coins that only have small transactions under $ 1000 per day will gradually be delisted from the market or exchanger. But altcoin which has a large community and has a large market cap value in my opinion will still continue to survive and may be a profitable investment
