Im quite sure you have a better alternative. Until everyone has a chip on the back of their hand paper currency and credit cards are the best way unfortunately.

I don't have a better alternative.

People are gonna greed no matter what. If we just trade for peices of squash instead of cash, people are gonna do the same thing.

I would like to believe Crypto + being self sufficient a better alternative. I haven't felt the need to get a job since a decade since i'm self sufficient in many ways. Tho i can pocket $ from crypto. Let say we removed $, not sure what alternative would be a good combo with Crypto to pocket gains.
