Long Term HODL and DCA?

I've been DCA-ing Bitcoin since January, and my average is $64K. I understand the long-term plan and I'm not aiming to sell at the peak. It's obviously very hard to time the market, but I'm still confused about why I should DCA if the price goes back down to $65K after the bull run in a bear market. Even if it reaches $150K, I'll be back to square one. Why not just buy when it goes back down? Worst case, my average will be higher, but I'm losing a lot of potential by waiting anyway. Sorry if it sounds dumb, but I don't understand why I should put money in if Bitcoin has already increased so much since last year.
