Let's say tomorrow everyone in the world starts using Bitcoin. There are 18,622,375 BTC in circulation right now (although thousands have been lost for ever), and the total supply is 21 million Bitcoins.
21.000.000 รท 7.8 billions world population gives us 0,00269230769 per person. (Meanwhile the Top 1% hold most of the BTC, but let's skip it for the moment).
So, you have 0,002 BTC for all your life. What would be the result of that? Imagine going on a store to buy a Coca cola, you would see prices like 0.0000000000035472.
Do you think that's a practical solution? Do you think most people would like that? I love Bitcoin, but this is one of its weaknesses.
