Did not do their research:
The guys who go arrive with a pocketful of Bitcoin, an online currency that's beloved in bad places because the cops can't trace it. You can buy yourself a shiny gun or some dope and leave no sign of a paper trail. You're anonymous, which is how everyone—all 700 r/girlsgonebitcoin subscribers—likes it.
Bitcoin’s exchange rate with the U.S. dollar works out to roughly one coin per $5, but it’s not exactly that simple. Since it’s an online currency, you can’t use it to buy anything in the real world, which negates the function of most stripping: to make quick, spendable money.
