I get your mathematical point of view, it all scales up. But then, afaik lots of people with lots of money invested at the end of 2017 to make the value rise only to sell their BTC shortly before the bubble did burst or shortly after. Lots of people did buy in shortly before the bubble burst to get their piece of the cake but actually lost hell of a lot of money. You need the same amount of "way too late"-people buying in again, and even more of them to make it scale in these mathematical proportions. But people and financial markets are chaos and not logical principles, thus the word risk investment. Though it would be awesome if that theory of amplified oscillation would be true, but for that it would need some resonating body to oscillate with, you know, some good press for it to get more mainstream adaption and people to buy in (again...). Maybe read some financial publications, these people might write some selffulfilling prophetic hype about it... or not...
My estimation is BTC will resonate around the 3k or 2k for the next few years and then either slowly rise or even fade into obscurity as better crypto currencies arrive, maybe even ether gets more mainstream adaption... Or bitcoincash... or or or
of course you could invest some 100k yourself and suddenly market cap seems interesting again as there will sure be a rise in value as demand increses for a short time. But then, send me some of your 100k and I'll invest it in better things.
