i think it makes sense a lot but my question remains what would happen when the 21 bitcoin possibilities become exhausted?. what if by then big businesses adopt it for their daily operation? can the price of 1 sats then reach 1 dollar! or would there be an adjustment on the blockchain code to produce more?. I need your view as an economist
Changing the source-code to produce more than the 21 mln limit would destroy 99% of Bitcoin value instantly.
The only reason Bitcoin is worth thousands of U$ is because it's rare.
Also a satoshi cannot ever be worth U$ 1 because :
a) there isn't that much money in existence and;
b) Bitcoin transaction fees would be impossible to pay if the smallest unit of the cryptocurrency gains to much value. You can't break a 1 satoshi transaction down into microsatoshis. That would probably require changes to the core source code, perhaps adding 8 more zeroes.
