21 million bitcoin might not be completely available as there are so many of those that had been lost in the air but the best thing here is that Bitcoin is divisible buy satoshi and that is the best part.
there are even saying that 1 satoshi will be 1 dollar in the future, imagine how much you can hold and gain having 0.001 bitcoin?
this must be the best investing tools people might have in their entire life.
With high demand, there will be always Bitcoin adopters willing to sell their holdings for profit. So it's the opportunity for those who don't have any coins to start accumulating their satoshis. They just have to be skilled at electronic devices and internet to set up wallets, create accounts at exchanges and to buy and sell Bitcoin.
For that reason, I don't think everyone can have Bitcoin, as there is still a high number of illiterate people in the world, especially regards the virtual world and the foreigner universal language, which is English.
Maybe in some decades this scenario will change, but by there that is what we know so far, consequently making it harder for BTC adoption to grow considerably among the masses.
Im not surprised by this blinkered perspective. You're right: BTC adoption relies on literacy and knowledge. But guess what? Just as humanity evolved from nomads to agriculturalists, from kingdoms to nations, it will also evolve in terms of digital literacy. Its an inexorable march of progress!
The elderly? Yes, they might not get the nuance of blockchain now, but with platforms like the internet bridging knowledge gaps, it won't be long before even your 80-year-old grandma knows how to move sats around.
The constraints of language and literacy? Temporary blips on the grand timeline of humanity. English, the so-called "universal" language, is just a present-day tool. Platforms are already emerging to break these barriers.
Dont undermine humanity's adaptability. Bitcoin's adoption may seem constrained now, but to suggest its limited by today's literacy issues is a narrow view. History has shown us time and again: humanity adapts and evolves. So will its relationship with Bitcoin.
