We see it every time Bitcoin goes to a new lower level.
Bitcoin "believers" will hurry to say "buy the dip" and "just wait it will come back"
Reality is that every dip is a new lower level - and after that comes another dip...and another.
In the beginning of 2017 very few people had Bitcoin - and therefore the price could quickly move up as a large number of people with zero financial understanding started buying Bitcoin.
Now a large number of people with zero understanding has Bitcoin and price moves down - there are no more new fools to get into Bitcoin to ever pump it again.
"Buy the dip" is something only fools believe - and as can be seen in here there are unfortunately many fools in here who do not understand that their money is already lost
You might have such views regarding bitcoin based on your journey and experience with bitcoin but what I think buying the dip which is specially this period of time is the best things that can done by an investor or a trader because the income margin they can gain from a single investment is very high but some chose to leave the market instead of taking an advantage of the situation so bitcoin tends to fall but in the near future definitely they will understand what they have left because bitcoin is definitely progressing so any long term investor who purchase after the dip can make huge income if they have patience and confidence
