Average bitcoin $BTC price 2020-2024 halving cycle was 34k.
A bit below 2019 S2F prediction of 55k, but still in normal range and not bad given #BTC<4k when prediction was made.
S2F refit with new data since 2019 shows similar parameters & results: ave 0.5m 2024-2028 and 4m 2028-2032
When bull and bear markets occur: bull around halvings (from ~6 month before until ~18 months after H) and bear between H. This is what S2F adds on top of NgU of time based models (like "power law").
