You’re right, trust is the biggest issue with stablecoins. Even if some prove their reserves, many people still worry. It’s normal to be cautious since money feels “out of thin air,” but transparency helps build confidence slowly.
Stablecoins are important, i don't know about trust part of stablecoins but i am only interested because of its stability in value. Most countries have their local currency paired with stablecoins. Exchanging and holding stablecoins over traditional fiat helps lessen the worry about inflation and currency devaluation, they have own flaws but it is okay to see their importance.
