Even if you don't like Tether or fiat, the market, particularly underprivileged ones, want something like this clearly. It creates a much lower friction ramp from BTC into the fiat world and vice versa. It's also much easier to imagine my blue pill corner store integrating with some kind of stablecoin service than outright accepting Bitcoin.
I don't have the faintest clue how this works in detail though. What's the path to understanding it? Grokking Omni tether?
