Most people are poor investors in anything from stocks to education, to family and friend selection. Fact is bitcoin has been dipping off and on for a decade only to suddenly make new impressive highs.
Simply look at a graph at bitcoin prices over the last ten years and be a judge for yourself.
Don't "buy the dip" and stay poor. There remain plenty of jobs at McDonalds and similar low paying places where you can settle comfortably drinking beer in front of your television at night.
