So basically you are saying we should just buy Bitcoin immediately after halving and then we should hold it until a few years because as far as I can see it takes a few months after the halving for pump to begin.
That is up to you, and you have your money, you are free to buy bitcoin right now or later
But if I were you, I will buy bitcoin every time the price is down, and sell it every time the price is up. But I don't forget to save some amount of bitcoin to prepare for selling in the future because I am sure the price will be at the highest price. We are near the end of this year, and it's only 2 months later we will see the next year, so I don't want to be late to buy bitcoin at a low price.
