Buying during a dip yes is quite strategic but you'll also miss a lot while waiting for a dip.
Everyone should buy according to their financial capabilities, if you don't have much to buy, and decide to wait for a dip is alright, and if you are financially capable to buy at anytime it's still alright.
N/b you cut your coat below your size and not according, if you want to be a success!.
If you are afraid of missing the moment while waiting for the price to drop, then you should use a buying pattern using DCA to have a little adjustment. For long-term investments, it may not affect the purchase pattern because what we expect is a significant increase so that buying at any price can be an option. But if you want to maximize all the possibilities that exist, apply a percentage of purchases where you buy consistently using the DCA pattern and wait for large purchases when there is a decline so that both can be much more optimal as an investment effort that we make.
Yes, we always recommend that investors should invest consistently over the long term using DCA without worrying too much about market fluctuations. Rather than investing aggressively in large amounts at once, it is better to invest a certain amount regularly through DCA continuously, because this will allow you to grow your portfolio at a long-term average price, which will greatly increase your profit.
And by keeping a reserve fund ready, when the price is a DIP during market volatility, you should buy more Bitcoin in that DIP. Strategically buying a large amount with the reserve fund during DIP/fall, it will bring better success later.
