What does frequent basis mean? It seems that cash is already on the minority even today by some definitions: https://shiftprocessing.com/cash-vs-credit-card-spending-statistics/
@A Stores don't encounter it often, I don't see a good reason to carry it around with me anymore, stuff like that.
@IsaacKing You're going to need to add some metrics to this market to make it playable. The only cash I ever carry with me is from foreign countries, because I only ever take cash out when traveling abroad, so that's what sticks around in my wallet.
@IsaacKing Retail cash usage drops below 5%? https://www.statista.com/statistics/568523/preferred-payment-methods-usa/
@IsaacKing I haven't been carrying cash with me for years. Maybe do resolution like "out of X random people that I ask, Y will not have any cash with them" or the same but "haven't used cash in the last Z days"
