The best way to come up with a betting investing strategy is to create a bunch of investment charts showing lines going a certain way and then saying that when a line does X, then the market will do Y.

If you convince enough people of that, they will do Y when they see X.

Then when you instead do Z while they do Y, making money you remind them that it did X but it was part of some bigger pattern of XYZ which you knew about because you are so smart with patterns. So the next time they see that...just do Z. Then you do the opposite.

And on and on...and now everyone knows all these crazy patterns and buys these tools and make money on selling the tools and teaching the patterns and coming up with new patterns...

Fortunately most Bitcoin traders do not follow those patterns so they just come up with their own strategies and the patterns become irrelevant. Until someone convinces enough people that the patterns exist.
