Actually, the second spot indicated by an X was, indeed, the safest place to enter to achieve the most gains in the shortest period of time.
I remember Willy Woo also posting something along these lines. Granted, it was only about 4-5X, but in a short order and without sudden catastrophic plunges.
It was a great place for a small leverage, too. Sure, you could have bought at 6-7K (indicated by a start of the bull run), but if you did anything else, but a straight cash buy (no leverage), your position would have been eviscerated. We had one glaring example like this here-a mindtrust guy, who became "famous" for an aggressive accumulation between, maybe, 3k and 10K, and then selling all in panic at around 4-4.5K during the Covid crash. You might think that this kind of a sudden plunge would never occur again, and you could be right, but it is unknowable.
For someone looking for a quick gain that was definitely the best point, and the most risk-free. But it's more obvious in hindsight.
But who knows how long we can rely on the previous cycle performance. You never know if next time will be different ....
