Trololo
Briz Trololo Lines Logarithmic Regression - Bitcoin Halvings Using logarithmic (non-linear) regression curve Trololo Lines to forecast the BTC (BLX 1D) price range, and it's trend within the range - based on previous trends influenced by the halving every four years.
Not as exciting as Stock-to-Flow models, but pretty close up until 2023 when Stock-to-Flow launches from 100k in 2023 towards 1 million in 2025 (not shown) - Trololo Lines say otherwise.
If BTC price bust 100K by 2021 and stay above it, then I may negate the Trololo Lines - but until then, this chart will be my guide (NFA).
