It seems that profit is very easy if we think it's easy, unfortunately many people are too afraid to buy for fear that the price will go down, and in my opinion the best thing right now is to buy immediately, if we focus on long-term hold then we have a chance to profit 100x or more but if we make it daily trading then immediately sell when it has a profit of at least 5%.
And I think the analysis is still valid up to this point, with the recent SEC with hunt against exchanges, we've seen the price going down to as low as $25k, in which the graph being drawn up by the OP can't be seen along that line.
So good for him, if he was able to sell because of this analysis and take the profits. Although I would say that I did sell around first week of April, not because I think it's the perfect time, but I needed some money for emergency purposes and looking back, I would say that I timing the market right as well as it is way above what the current price. But I have to get it back right away though, some DCA to continue stacking sats.
