I agree, the truth is this makes me remember that on the Spanish board I said something like that and I didn't know that leaving some discretionary income to buy on the dip was a variant of the DCA method, because the DCA method consists of buying daily, weekly, monthly whatever the quota of money to accumulate, I thought that some other income to buy on the dip was another strategy or method and no, it turns out that it is the variant, but it is the safest way to do intelligent DCA work.
If you are buying regularly with the DCA accumulating strategy, their is no point disturbing yourself about the dip because you can equally buy the lowest part of the dip through the dca accumulating method, since you will get to buy at every price interval regardless of it price.
What Investors are advised to do is to always have a reserve funds in place so that when their is a dip in the market, you can use your reserve funds to buy and accumulate Bitcoin aggressively then, but if you have no reserve funds in place while accumulating Bitcoin through the dca accumulating strategy, their is no point doing more than yourself because the DCA accumulating strategy is quite ok, and your investment will be fine as long as you stay on track while accumulating Bitcoin weekly or monthly.
