Does the “there’s a sale on!” Mentality every time that there is a dip in the market worry you?

This type of mentality seriously scares me, that there is absolutely no way to lose if you’re in it for the long haul and looking to future retirement or something.

Admittedly I’m not the most financially literate person on the ins and outs of the stock market or other types of investments, but every time I see this type of post or comment, I’m reminded of the frenzy that the cryptocurrency market was in when bitcoin was on its meteoric rise in 2017, and how every dip only represented a flash sale before the next all time high was beaten.

Does the current state of events not seem akin to this, albeit just on a larger, and slightly slower scale?
