How to catch the falling knife?

When Bitcoin was going down I felt I had to use Swan and stare at it to catch it on the away down and guessing how far is would go.

The bounce was too fast so it ended up overshooting.

Whereas outside by iron in Bitcoin I could use limits and this was better to some degree. It caught at lower tiers than catching a falling knife. But one limit never picked up and was just shy of the bottom so never got picked up.

In general I DCA hourly because of the volatility but how do you make a move when things are volatile and going down?

The other approach I have was just a general “good price” and just get it and forget about missing the dips. So I had been mid $55k for both this and the prior dip and thinking it may not go much below post etf.
