Venezuela is an interesting case in the sense that it is an otherwise well-off, decently well educated country going through a crisis.

My country - India - has the world's largest number of poor. Even if these people were to get smartphones, there are already deeply entrenched players (PayTM, Google Pay) who offer free and instant transactions.

This is true for a lot of African countries as well. No reason for anyone to use a new currency when there's already M-Pesa and UPI and PayTM that use the currency they already know and trust.
