(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.
