Good for you mate, and as what others suggested you should have buy back and that's what you did. I also did DCA for quite some time and will continue to stack sats even after the block halving. In short just buy as much as we can, or as what our budget can afford.

And let this be a lessons for others though, even if we sell, there is still a chance for us to buy back. It might take some time though as we all know that DCA strategy could be tailor fit to your budget and strategy.
