I would like to think that digital applications played a huge part for this. A lot of people purchase online, view their accounts on their phones, and pay with their cards or phones. Physical cash isn't as important as before. This made the introduction of stablecoins easier. Since they are pegged to a dollar, there isn't much difference from what they're used to. Add to that the different advantages it offers like protection from inflation, less fees compared to credit cards, and more control over the money.
