There will only ever be 21,000,000 #BTC.
Your cost of living will always trend to 0 on a #Bitcoin standard because BTC is infinitely divisible.
You can divide 1 BTC into as many units as you want to, but this doesn't mean you have more Bitcoin.
Each BTC can be split into 100,000,000 Satoshis (you can almost think of this as Dollars = BTC and Cents = Satoshis).
1 Satoshi = 0.00000001 BTC
There are a total of 2.1 quadrillion satoshis.
Satoshis can also be divided into smaller units if needed.
Having a form of currency that is infinitely divisible means that you can value things in smaller and smaller denominations.
It also means that ANYONE can save in Bitcoin, and the value of their savings will increase over time.
They can use their savings to buy whatever they want.
Compared to Bitcoin, everything is abundant.
You can build more houses, grow more food, and make more cars.
But once 21,000,000 BTC have been issued, no more new coins will issued.
Ever.
As Bitcoin's price rises, the people who own some will be incentivized to exchange their coins for whatever they've been saving for.
Entrepreneurs from around the world will be incentivized to produce more goods and services to accumulate smaller and smaller fractions of BTC.
But over time, their tiny fraction will be worth A LOT more because...
There will only ever be 21,000,000 #BTC.
