The exact same thing happened in the '90s with online purchasing.
At first everybody thought it was crazy. "Who would give their credit card details to people over this new fangled Internet thing?" There were legitimate businesses and total scams. But things grew and grew, and now nobody bats an eye about one click purchasing on Amazon.
I figure this will go the same way. Right now it's the wild west, but things will settle down and eventually nobody will bat an eye about spending a few doge on an impulse.
