This chart has nothing to do with the short term, so where you buy BTC doesn't matter In this term b/c as long you end up selling at a profit, then you did better than most other investors in the market.
This Data is using the US Election dates with a correlation to BTC Tops and also uses the Coinbase #1 App dates to find a correlation to the BTC top.
Neither one of these are perfect but when things are euphoric in the future it will be hard to determine when is the right time to sell. At times in the past i have not had an exit plan so I was left holding the bag... (still to this day from 2017 lol)
Next time around we will be able to use these dates and events to determine when it will be a good time to take profit based on past historical events and how the BTC top played out based on those.
Let's see how it plays out... None of this is Financial Advice...
