Just posting this mostly because I finally figured out a way to use sine waves that's meaningful for BTC so far. One wave, fixed x location... different y locations.... so simple.
Fits the data pretty decently too... so I figured I'd take a guess at the rest of BTCs life. 2040 approx when I say it dies... is when the last BTC will be mined, for those still using it (even though it likely will be very, very, outdated by then). 2025 maybe as a End to the festivities at about 50k. Who knows, I just felt like putting it at 0ish.
Definitely trading advice. If you want to lose your money, probably not advisable.
