The DCA strategy doesn't work with the current price of bitcoin, it works with your discretionary income so regardless of what the current price of bitcoin is if you are investing using the DCA you should still be buying bitcoin continuously unless you run out of discretionary income, bitcoin investment is long term and if for that entire time the price of bitcoin keeps going up will you decide to not buy simply because the price won't come down? That's not a very smart move, so instead just keep accumulating as long as you have your discretionary income available to you.
Good point, it doesn't matter whether the price is high or low, it's a strategy that requires consistency which means that investors would definitely buy during dips and when there's a surge, that's why to many investors it seems like the best strategy and most talked about, it's very effective for investor who prioritize consistency in accumulating Bitcoin.
Some people like to wait for dips to buy when price is lower but with the DCA waiting is unnecessary cause they'll come across different dips and highs cause you're constantly buying.
