Real talk, not everyone will have access to crypto even in the future. This "Crypto Dream" will not be acheived because we still have many issues about technology all around the world.
Why so? Most people in most countries
(yes, most. not all) already has access to internet connection and mobile phones; that should be enough for them to have access to bitcoin. It's just going to be signifiantly harder for them to move back and forth from bitcoin<->fiat if the country doesn't have access to an exchange like Coinbase or Abra; though LocalBitcoins is available almost everywhere I think. If not, they could potentially just trade bitcoin peer-to-peer in person or online.
Plus not everyone can afford one.
Why not? If you have only $5 for instance, you can trade that $5 for $5 worth of satoshis
(0.0013 BTC as we speak) with someone using minimal fees . Daily reminder that you don't need to own one whole bitcoin.
