I realize that's my mistake of not understanding the 150 day moving average well enough. I've just rechecked it and realize what I was doing was making no sense in regard to DMA.

What I was doing was simply to take the price growth over the last year of roughly 1000% and extrapolated this. This wouldn't put Bitcoin price above 10k but closer to 9k as I've just calculated. And I'm not sure about my math at all.

I'm not sure your math about the 150DMA is good either.

Here's one interesting graph I found on the 200DMA.
