Some people would have researched a particular instant exchange and see how reputable it is before using it for their swaps, while some may only afford to take the risk and see if it is up to the required standard to be trusted.
Fair point, and for the second group the test should cost as little as possible. The minimum is about $50, the rate is fixed so you know exactly what arrives, and if you add a refund address a failed swap goes straight back to it. If you feel like trying us that way, a small first swap is exactly how we'd want to earn it, and any feedback here, good or bad, is welcome.
