Wow... Someone in "crypto" subforum actually asks this...
Because cryptocurrencies will be a completely normal way to pay for products and services in near future?
Because a lot of people nowadays want to be paid in crypto by default instead of fiat?
Maybe because a lot of us can't stand PayPal and similar services, so cryptocurrencies are a way to avoid those?
Maybe some people don't have any need to take all of their payment right away to spend it, and they can hold it in the hope their coins/tokens will have a higher value in the following months?
Maybe because payment is almost instant?
