For this theorie, i just looked at the decreasing of percent for each all time high to the next one.
This is like x 64 ... x 32 ... x 16 (but not so accurate)
We saw a major bullrun from 0.39 USD to round about 30 USD ( ~ 77x )
We saw the next ATH at 1 143 USD ( ~ 38 x )
We saw the last ATH at 19 417 USD ( ~ 17 x )
The multiplication is cut in half each time. Because of this i predict the next 2 ATH just by using simple math:
19 417 x 8 = 155 336 USD
155 336 x 4 = 621 344 USD
In the chart, the values are not perfect because of scale, but i think you get the point ;-)
No financial advice!
I just want to leave it here and visit in 2021 and 2025 :-)
