It's is possible to make 1 billion people adopt and start using BCH in a global scale?!
My answer is "yes".
If the BCH Ecosystem get focused in emergent markets, such Africa, of course the community can grow and reach astonishing numbers.
why I believe in that?!
Let's start knowing first the continent.
Africa is a Continent of almost 1.3 billion people, composed majority by young people and suffering with unemployment and looking for new opportunities to earn, pay and get paid in a complete decentralized way, as the local payments despite not being that much, for a African reality cost a lot in fees.
Also to mention that the continent is unbaked in the most part of it, representing a big percentage to adopt BCH as more than 70% of it's population are not linked to an Financial corporation "Formally" but using services that allow them to store value and use in daily routines, the e-wallets that, are used for almost all the people in the continent banked and unbaked.
As mentioned above, the constant look for a services of payments and the ambition of empowering the masses is driving the young African to find payment solutions and works that can mitigate the aspirations, and help to succeed online and the concept of peer-to-peer cash system of BCH with faster and cheap fees, suits in the needs that are wanted in the continent.
The only way of payment that is used widely, the e-money supported by local telecommunications companies are expensive, centralized and with limits in cash withdrawals.
In contrast the BCH asset is a best way of peer-to-peer, descentralized, with no limits to withdrawals, transfers in a complete safe environment, where the user is the "unique responsable for his money.
But how to teach the societies about BCH?!
This isn't actually a big deal as the continent still Emerging into Cryptocurrency and the major assets like BTC, are the ones well know in the continent, the first to do is teaching the Young's about BCH and a way to do that is to have Ambassadors of the asset spreaded in the societies.
There must be houses of BCH community in almost all the prominent locations in Africa and from there to gain ramifications to other places in the continent.
Prominent countries in crypto, may be considered the ones who got a good number of people with knowledge in Crypto, must be much attention here as many Nations doesn't know Cryptocurrency but only BTC, and that makes a lot of confusion.
BCH can grow a lot in Africa and the adoption reach numbers surprising even the biggest communities around the world, only needs Literacy and some investment in people who has the interest to present and advocate about the ecosystem in Africa.
A fun situation that make me believe that We as BCH community have much to gain in Africa is the unknown knowledge of other assets than BTC, as most people, even Investors doesn't know more Cryptos only thinks that BTC is the asset that can make them have returns... and most trades are based in local WhatsApp or telegram groups.
Africa has a lot to offer and learn from BCH and needed Investors and people with power to spread the word about!
Let's promote the BCH Ecosystem in Africa and works as one to make that happen and see the BCH as a peer-to-peer cash.
I agree with you, people in Africa could benefit hugely from knowing about and being enabled to use Bitcoin Cash.
In many ways they are already ahead in being familiar with mobile money. Cryptocurrency with sound money like Bitcoin Cash is a natural step.
