It’s high time for Bitcoin (BTC) to begin its next significant price rise, the creator of one of the best-known BTC price models says.

In a tweet on Sep. 14, quant analyst PlanB highlighted increasing signs that BTC/USD is due to repeat historical gains.

Referring to the original incarnation of his stock-to-flow (S2F) model, PlanB said that the time was right to begin an order of magnitude step up.

 “You see the jump in model value at the halving (white line) and corresponding drop in S2F multiple / model error (white dots). Time to go up.”

“This is the 2019 time series model on historical BTC data only (no gold, silver, diamonds, real estate data used),” he wrote alongside a new chart.

The original S2F chart differs from the more recent stock-to-flow cross-asset (S2FX) model, which incorporates macro factors and introduces “phases” in Bitcoin’s metamorphosis as an asset. It calls for an average BTC price of $288,000 before 2024.

Since the May halving, Bitcoin has put in “red dots” on the model, which have run to expectations, if not in a similar fashion to what happened after the 2016 halving.

Interestingly, Cointelegraph market analyst Michael Van de Poppe is also seeing the same pattern emerge from a technical analysis perspective.

“If you’d like to compare periods and market cycles, the current state of the market is comparable to 2016,” he tweeted on Sep. 14.

“Slow upwards grind, with long sideways consolidation periods. In 2016, several were seen. In 2020, 2021, it’s likely we’ll see that too.”
