In the future, more and more altcoins will be listed through ETFs. For some coins, being listed through an ETF is a lifeline, but for others, it is just a nice addition.

Of course, this does not mean that as long as a coin has passed the ETF, it can be bought mindlessly. The ETF approval for altcoins only guarantees that their lower limit will not drop to zero, but it does not guarantee a skyrocketing increase.

Based on the current market disclosures, the mainstream coins that I personally have the highest hopes for with the addition of ETFs are: SOL, XRP, LINK, DOGE, HBAR, LTC. As for other coins like DOT, MOVE, XLM, even if the ETF is approved, there won't be significant capital entering these coins; their future market trends will more likely be linked to a few other mainstream ETF coins.
