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.
I think a better set-up would be like this> 80% for BTC and 20% for ETH but I prefer this set-up better> 100% for BTC. No need to waste our money, time and effort on other cryptos because all of them are only depending on Bitcoin. If BTC falls they also fall although if BTC pump they will pump but I think our profit potential is still the same or have gotten lesser than if we put all our of money in Bitcoin.
Many projects are only promising at their earlier runs but once they dump they will hardly recover anymore so don't ever mistaken their dump as a good opportunity. We are not holding for no reason but all of us are doing it because we want to earn a massive profit.
