Used the BTC logarithmic growth curves indicator, as well as fractals from previous cycles, extrapolating them out over an extended period of time. I believe from cycle-peak to cycle-peak will take about an additional year with each passing cycle (2013 – 2017, 2017 – 2022 or 2023, 2023 – 2029 or 2030, etc.)

Eventually BTC price fluctuations will smooth out, and day-to-day volatility will look more like the stock market, with 0.5 – 1% daily moves being viewed as significant. I think by the 2040s, after the 8th halving when the block reward will be less than 0.20 BTC , 1 BTC will be between $10 to $20 million and the price will become relatively stable. Of course, anything could happen (looking at you, Putin) but I think this is the general direction we’re heading toward. BTC is mathematical and monetary purity.
