I gave you a merit for sharing this chart, but...Let me share my thoughts on this. If you rely to much on this chart to sell your bitcoin, there is a higher chance you won't make it as you may think right now. The are a few reasons for this. If you look at the original site and look at that 2nd chart, you can see that it's very hard to predict the right timing.
Those who watched this chart in the previous bull market 2017/2018 have missed the top and didn't sell at the top! Because it simply did not reached the level of the previous tops!
The second thing, if you want to sell a little bit sooner like it happened at the 20.000 usd, you would miss a lot of potential gains if it continues to the previous top levels.
The third reason why this is gonna be even harder to achieve is that many hundreds if not thousands of new traders will look at this chart to sell. Imagine everyone wants to sell at these levels and no one wants to buy there. What would happen? It wouldn't work. So the best thing you can do is that if you really want to sell at those levels, to sell in a dollar cost average method. Even better if you use this chart only as one of your many indicators combined so you can get more accurate the biger picture. That's the best thing you can do.
