Sometimes folks wait for a certain size dip, such as 20%, yet it might not do you a lot of good if you had been waiting since $27k for a 20% dip and then finally you get your 20% plus dip, but the dip is ONLY down to the lower $50ks.. Another problem with waiting for any dip is that you might get several dips that almost meet your threshold but not quite, or alternatively they meet your threshold and then you end up blowing your whole buying on dip amount, while the price keeps dipping.
Now essentially buying the 20% low dip is impossible because we are currently in the pre-bull market period. If the DCA approach is the best current time to invest in Bitcoin, and the Bitcoin market is dumping for the current period. In general I think it would be possible to buy bitcoin dips with the accumulated money, and investors would have to wait. And as soon as the Bitcoin market is dumping, the money should be supplied and prepared for buying Bitcoin Deep quickly, while the regular investment in the DCA method will continue.
Surely, there is no exact formula, and a person surely has to figure out how early he might be in his bitcoin journey and maybe consider that his main emphasis might be buying regularly no matter what, even if he might have a side hobby of buying dips, and surely if someone might have been accumulating for a whole cycle or two, then he might be more discriminating in regards to how much dip he wants to get, and not be necessarily prejudiced if he misses his dip buying targets.
Of course, this is the right approach, an investor has to figure out for himself how to invest and fund. And all kinds of help and support and how to keep the investment for a long time, you can get all such support from JJG. So currently only preparing for Bitcoin DCA method and deep buying, but the longer you hold Bitcoin the more profitable it is possible to get from your rules.
