You are absolutely correct but our focus now is not buy the Dip reason because the Dip doesn't just occur every day or anyhow, remember if you said our focus is to buy Dip and the market haven't that means we won't buy Bitcoin right? perhaps our focus should be accumulating and holding regardless of the market price which is the DCA method or strategy.
If you are using DCA strategy for investing then why wait like a fool for dip time. Dip buying may not be easy for those who are just starting Bitcoin investment i.e. new investors. Also, waiting for the dip period in the market is also foolish, many will stop his investment only considering the dip period, while he has enough opportunity to buy bitcoin continuously.
Dips are unpredictable, so rather than waiting for this time to invest, one should be ready to buy bitcoins continuously by determining a fixed source of income i.e. buy bitcoins immediately. By buying Bitcoin regularly you can take advantage of any market timing.
