you will remain poor no matter what currency you are using and whether it adopts a digital system or still using physical currency, the assets you have are same. hackers will also think of spending their energy to steal less money from poor people.
Same as i was thinking! Poorest of the poor currently can already be considered as cashless as they dont rely on physical money but on services provided by the government and other private sectors. In the event that physical money is not being used anymore, it wont really be that much difference for the poor people
