Some dips happens for a short term, but others happens because the project itself has issues. Issues like maybe poor management, total abandonment etc. That is why every dip isn't a buying opportunity. Buying blindly into every dip without getting to know what caused that dip is simply unwise.  Based on what you said on confidence, I would say this The Crypto market is highly volatile and as such Confidence without Research is Null Before one invest into any dip, this are the questions you are meant to ask yourself:
1) Is the project a solid one?
2) Is there any tangible reason that this project will bounce back or recover? If your answers to this is uncertain, it is better to wait it out
