If a new investor that his DCA is ongoing consistently, and he has $1000, he can chose to share it into three parts whereby he uses $300 to lump sum, $200 to buy at the dip and $500 to DCA with $50 for 10 weeks. The important thing is that your DCA should not stop but keep buying for a long period of time.
Tweaking from one strategy to the other will depend on the size of your bitcoin portfolio and how best you understand using those different strategies.

The important thing is that DCA should be the main strategy for accumulation, while the others can follow the flow of money you have including beginners who are just starting out.
I prefer the main DCA strategy to be weekly.
Trading funds to anticipate when the price drops then ready to buy it.
