We can see not only the S2F(Stock-to-Flow) but also the S2FX(Stock-to-Flow Cross Asset) model announced in 2020.
In this model, bitcoin is treated as comparable to such as gold .
These are known as "store of value" because they retain their value over time due to their relative scarcity.
Bitcoins are scarce.
The number of coins in existence is limited, and the rate of supply is at an all-time low because mining the 2.2 million outstanding coins that have yet to be mined requires a lot of power and computing power.
The Stock-to-flow ratio is used to evaluate the current stock of a commodity (the total amount currently available) versus the flow of new production (the amount mined in a given year).
The higher this ratio, the more scarce the commodity is and the more valuable it is as a store of value.
█ How To View
On the above chart price is overlaid on top of the S2F(X) line. We can see that price has continued to follow the stock-to-flow of Bitcoin over time. By observing the S2F(X) line, we can expect to be able to predict where the price will go.
The coloured circles on the price line of this chart show the number of days until the next Bitcoin halving event. This is an event where the reward for mining new blocks is halved, meaning miners receive 50% fewer bitcoins for verifying transactions. Bitcoin halvings are scheduled to occur every 210,000 blocks until the maximum supply of 21 million bitcoins has been generated by the network. That makes stock-to-flow ratio (scarcity) higher so in theory price should go up.
The stock-to-flow line on this chart incorporates a 463-day average into the model to smooth out the changes caused in the market by the halving events.
I recommend using this indicator on a weekly or monthly basis for BITSTAMP:BTCUSD .
