"In 2015, when I bought my first btc at $400, people said bitcoin was dead.
Bitcoin is not dead but stronger with time and people get more boring to call "Bitcoin is dead" that is shown in the following summary chart.
https://99bitcoins.com/bitcoin-obituaries/https://buybitcoinworldwide.com/bitcoin-is-dead/Today, btc is $40k, and S2F model predicts $532k after 2024 halving. People say it is impossible."
It is possible but after 2024 halving is vague prediction with time.
After 2024 halving can be 2025, 2029 or 2033. The prediction must be clear and related to time. Without time, it is a trash prediction.
PlanB model is wrong. The S2F algo predicts a 2x increase in supply every 4 years and this leads to an exponential growth. This should look like a straight line in a log graph but the growth of BTC is curved in a convex fashion (downwards). There is a very precise law for the growth of BTC and it is what I call the BTC Scaling Law.
