Why I think BTC in its current form is unsuitable as a currency.

In this post I'm going to lay out why I don't think the utopian vision of the world abandoning fiat for BTC as the primary global currency (1 BTC = 1 BTC) is possible.

The TL;DR is that BTC's ever-dwindling supply does not work with an ever-growing human population. All numbers below are googled.

Total number of sats in 21m BTC = 2,100,000,000,000,000.

Average wealth per human is $84718 as of 2022.

Total human population = 8.1 bn

Since 1 sat is the lowest possible unit of BTC, we can assume 1 sat is the equivalent of "$0.01" should the world ever transition to BTC as the primary currency. Otherwise we would have trouble paying for tiny things like a small candy, or lose the ability to accurately price goods and services.

That would mean each human on average would need to be in possession of ~8.4m sats.

8.4m sats * 8.1bn humans = 68,040,000,000,000,000

That's ~34 times more sats needed than will ever be available.

This is before considering:

• That 21m BTC will only be fully mined in the year 2140
• A significant chunk has already been lost thanks to Satoshi and boating accidents
• As time passes, more private keys will be lost here and there taking more BTC with them
• There will only be more and more humans as time passes.

So… there's no way BTC in its current form will be able to function as a currency. Please feel free to poke holes at the above, I'd like to be proven wrong!
