When ADA broke yearly support level it didn't free fall right away. It had a retest that has been rejected big time. Now i personally can't see a reason for you to knife catch it, unless you are looking at a bigger picture and you are starting to scale buy all the way down as a long term investment.
I would swait for the demand zone where everything started back in Dec, 2017. Thats where price will be more interesting for investors to buy in again.
