I agree, among all tokens and coins If I will be asked what will be the best investment for the next halving? it could be bitcoin or eth. Spending your money to top 1 and top 2 coin in the world will not be useless even though they may encounter some dip in the few days still there will be a greater chance that it will be bounce back again, everytime I will have some extra I always converted it to bitcoin.
Bitcoin, no doubt.
And then ETH and the other altcoins will come to follow bitcoin's halving effect and that is to increase in price and value. Having the right time to buy during the dip is the perfect time and opportunity. That's where people have the problem of not being satisfied because they think that it's not a good time to buy when the market is dipping.
