Yes, in many places metal coins are still used; just imagine then the use of USDT, cryptocurrencies, and so on.

Stablecoins should be easy to use, but they often are not. The problem is not the asset itself, which is stable, but the workflow surrounding it. When networks are overloaded, users have to obtain a second token just to transfer dollars, making even basic transfers a headache. It's as if the technology hasn't matured enough.

Plasma is an interesting example. It does not attempt to be a comprehensive solution but focuses on a specific area: the predictable and stable settlement of stablecoins, even during times of high demand. If it can maintain fast transfers, reasonable charges, and stable behavior, it could change the way we view stablecoins. In the world of payments, reliability is more important than innovation, and Plasma could be a step in the right direction.
