Right time to buy?

Hi all, I am pretty new to crypto and dont know a lot, But up on till now ive been dcaing my assets keeping them at the same fiat worth. (As well as slowly increasing that fiat worth limit over time) For example if i have 1K of btc and it drops in worth when i check it to 0.9K id put in 0.1K and id do the opposite when it increases. Now with the 2 or 3 biggish drops on 7th sept 2021 20th sept 2021 and 21st sept 2021, im wondering if this is an unwise tactic and i should just keep an eye out for the end of the bear and buy in then? I currently don't know much about how to spot a bear run or when to know when it will end. Or is doing what im doing fine because it will eventually rise again and then i wont miss on buying at lowest point if i dont figure it out correctly?

Any help information and tips would be much appreciated thank you
