A digital wallet that supports or is compatible with lower phone versions. For example, in the past when I wanted to install a crypto wallet application but the condition of the phone was not adequate, in other words, it was not compatible with the device I was using. So here I hope that application developers can create digital wallets that can be accessed by the public there in general with the type of cellphone they hold.
Because today's technology is sophisticated and today's smartphone users don't have too many obstacles if it's only for transactions. The case may be with minimum fees and withdrawals if using an exchange platform. As for the micro income that supports digital transactions among the local community, it is quite difficult to accept. Because what they need is direct money without a third party that can cut the costs of sending and withdrawing.
Agree, the smartphone today can be as cheap as $25-50 for a very basic spec but can still work with any wallet provide there is a lite version typical made for transactions only. I think there are programs where manufacturers and telecom even 'sponsor' free smartphones for poor people to help them stay connected with the government to receive critical information. Especially in the rural region where floods, typhoons, volcano eruptions,... natural disasters happen annually.
So we got the hardware problem sort of. Next would be the internet fee which I think is even more challenging than minimum fees and withdrawals. Because for minimum fees and withdrawals fees, we can add some protocol where miners doing 'charity works' or community rigs only add specific txid from users/accounts come from that rural region. Same for exchange, try to get them to make a whitelist for those users/accounts too.
Free internet to maintain 24/7 connection for that rural region, now this is a problem. How about this: We get Elon Musk with his Starlink satellite internet to provide free coverage in that rural region zone, promise a good free press for him and his Starlink program as a return, more boost for him in the crypto world. What do you guys think?
