Scarcity, Value and Stock-to-Flow
Bitcoin, like gold, cannot simply be created arbitrarily, it is limited and finite supply to a max of 21 million Bitcoins, ever. Gold's supply has historically increased at around 2% per year. Bitcoin's supply will increase less than 2% starting at the 2020 halving, and will go to less than 1% a year after the 2024 halving. Bitcoin's supply will end when the last Bitcoin is mined approx. in the year 2140. Gold might be continue to be found through asteroid mining:)
"As a thought experiment, imagine there was a base metal as scarce as gold but with the following properties: boring grey in color, not a good conductor of electricity, not particularly strong [..], not useful for any practical or ornamental purpose .. and one special, magical property: can be transported over a communications channel" — Nakamoto
Bitcoin the scarce digital object. Scarce like silver & gold, but can be sent over the internet, radio or satellite; allows fractional ownership and rapid settlements; possesses a strong liquidity; runs on a secure ledger architecture.
"What do antiques, time, and gold have in common? They are costly, due either to their original cost or the improbability of their history, and it is difficult to spoof this costliness. Precious metals and collectibles have an unforgeable scarcity due to the costliness of their creation. This once provided money the value of which was largely independent of any trusted third party. " — Szabo
Bitcoin's costliness, caused by its costs of electricity to produce new Bitcoins. Gold and Bitcoin are different from consumable commodities like copper, zinc, nickel, brass, because they have high stock-to-flow (SF) ratio.
"For any consumable commodity [..] doubling of output will dwarf any existing stockpiles, bringing the price crashing down and hurting the holders. For gold, a price spike that causes a doubling of annual production will be insignificant, increasing stockpiles by 3% rather than 1.5%. — Ammous
A consistently low rate of supply of Bitcoin, like gold, is the fundamental reason it will maintain its monetary role also in future.
"The high stock-to-flow ratio of gold makes it the commodity with the lowest price elasticity of supply. The existing stockpiles of Bitcoin in 2017 were around 25 times larger than the new coins produced in 2017. This is still less than half of the ratio for gold, but around the year 2022, Bitcoin's stock-to-flow ratio will overtake that of gold" — Ammous
Gold has the highest SF 62 (current market value $8.5trn), it takes 62 years of production to get current gold stock. Silver is second with SF 22 (current market value $308bn). This high SF makes them monetary goods.
SF = stock (total supply) / flow (yearly produce)
Stock is the size of the existing stockpiles or reserve (total Bitcoin): 21 million
Flow is the yearly production/ creation: 657,000 (until next reward halving in 2020)
>> Bitcoin has (2019) a stock of 17.9 million coins and supply of 0.7m/yr = SF 25 (current market value $181bn)
Scarcity, as measured by SF, and directly drives value.
The Bitcoin halving will have a big impact on SF, indicated with the dark blue dot, the next halving in 2020 will double to the SF to 50, very close to gold (SF 62). The predicted market value for Bitcoin after 2020 halving is $1trn, which translates in a price of $55,000.
