My question is that is it possible for everyone to have bitcoin with the number of limited supply of bitcoin ?
Everyone can have bitcoin as you don't have to buy 1
BTC to have it. Satoshi Nakamoto designed Bitcoin with small unit, satoshi and you can buy small amount of satoshi but it still is bitcoin, just less than 1
BTC. The earlier you buy it, the bigger amount you can buy with same capital.
[Did you know?] Bitcoin Table of UnitsAs @Jawhead999 stated, theoretically everyone can have BTC but in reality, it is impossible for everyone to have Bitcoin or a portion of it. There are limiters and restrictions that make 100% of the population acquire BTC. Just like in the earlier replies, the limitation to access the internet, the illiteracy of one person about Bitcoin, the restriction of a country, and banning Bitcoin, limited access to devices that can process Bitcoin transactions, the interest of the person, and more.
They don't have to buy it, just claim it through faucet site.
We're talking about the possibility everyone can own Bitcoin, not talk about someone's desire.
When we talk about the possibility, we are talking about the realization of the idea and there are factors as I stated that limit the realization of everybody owning Bitcoin. Desire to not own BTC also hindered the idea of everyone owning BTC.
