(Not financial advice)
50℅ BTC
30℅ ETH
20℅ Solid top 100 altcoins/tokens (10 of them)
I think that this is the best setup.
Why shy away from promising projects just after their downfalls from all time highs? There's no reason if you're ultimately HODL'ing. It's completely fine to have some exposure in case you get a exponential return.
To me this seems like a solid strategy. ETH definitely seems promising and is widely held by many huge conglomerate companies, individual investors and crypto enthusiasts alike, especially because of its use in DEFI projects, for NFTs, etc. Many of these other "shitcoins" could still get some nice pumps. Ultimately though I think long term stick with BTC. Try to diversify but in the end I think all roads will still point back to BTC. Thats just my take.
