If by “a big cut” you mean maybe a few percent, and that most businesses take electronic payments anyway because there are advantages (people are more likely to buy stuff when convenient, accounting is easier, less risk of theft/loss than physical cash, etc) then sure, I guess.
If you think the solution is to make up a new kind of imaginary money that takes a shitton of energy to maintain, which has tons of different types (Bitcoin, Ethereum, whatever one was referenced in the initial comment) and would happen to greatly benefit those who happened to be early adopters (TOTAL coincidence, I’m sure)… No.
