I think the time frame for DCAing has passed. If you wanted to buy some bitcoins, you should have taken advantage of when the price was at $76k or something. That way, you could have already made profit even before bitcoin reached $100k again. By now, we should be happy and content with the coins we are holding and we should just wait for when the price hits the maximum target we have for our coins. This is just my opinion of course and if you feel that even with such a high price, DCA is still a smart strategy then by all means you should do that.
