like when bitcoin reached its ATH then many meme coins could increase sharply even though now they are down again.
ETH, BNB, SOL, TON I think it's best to hold and wait for the bull season to come.
Oddly enough, the bullrun that happened a few days ago was not like that, we saw Bitcoin price reach $73k, but for altcoin price it was sluggish, we even saw SOLANA getting worse in the last week... it proves that not every bullrun that happens to BTC affects altcoin...
I still agree with holding for ETH, it can be a priority for altcoin, because ETF really has a big impact like what happened to BTC a few days ago... I'm sure ETH might follow in the near future.
Bull run that happened a few days ago? You mean that short price increase, right? Do you consider that as a BULL RUN?
Always take note that bull runs in whatever market it is lasts for weeks, and not 2-3 days only.

What happened last week is just a short increase towards the price of Bitcoin, and that's all.
Anyway, I also like the coins that's being shared except for TON. ETH, BNB, and SOL had been on the top for a very long time, but TON? Nahh it's just the hype that made it on top, and when the hype is gone, there's a chance that it's market cap might not increase since nobody will buy the token anymore. Like you though, I also like to prioritize buying ETH because... why not? I mean it's the top altcoin right now.
