PlanB, the creator of the widely followed Bitcoin (BTC) price model known as stock-to-flow, suggests that those planning to invest in Bitcoin should avail of its current trading level below $40,000 while it lasts. Considered an authority in the crypto industry, PlanB expects Bitcoin to surge significantly above these levels in the coming years.

In a recent post on the social media platform X, known formerly as Twitter, PlanB suggested that the days of Bitcoin trading at its current levels are numbered, indicating an impending bull market. The creator of the stock-to-flow model used realized price data to back his bullish stance.
The realized price is derived from the sum of all BTC prices at which they last moved, divided by the current supply. It presently stands at around $21,000. According to PlanB, Bitcoin bear market bottoms are marked by spot prices falling below the realized price. Conversely, bull markets commence once the spot price surpasses the realized price levels for coins that were last moved within the last two years or five months.

PlanB expressed that he does not predict a decline from the current levels but confidently expects an average BTC price of at least $100,000 between 2024 and 2028. This timeline coincides with Bitcoin’s next halving cycle.
Despite the criticism received over PlanB's stock-to-flow model during Bitcoin's 2021 bull market performance, multiple forecasts holding a six-figure prediction for the next cycle are increasingly prevalent. Analysts expect a surge of Bitcoin price up to $130,000 by the end of 2025. In addition to this, another analysis anticipates Bitcoin's halving in April 2024 to jump-start the prices towards approximately $46,000.
PlanB described Bitcoin's current phase as a "pre-bull market", implying the actual surge is yet to materialize in the future.
