Not sure about that. Perhaps if they're super convenient to use. But if I'm going to put in the time to set up a system to reduce fees on FX conversions, I want to be sure I'm getting (close to) the best rate possible.

If they start charging 1% tomorrow, up from 0.5%, I'm pretty sure I would reconsider if I were using them (and I have used them in the past, in the early days -- they're great).

But I started routing currency conversions through an account at my broker (Interactive Brokers), and I'm currently getting market rate + 0.2%. These 0.3%s add up fast if you're converting meaningful amounts of money and in comparison Transferwise seems expensive again. But of course it's still a long way from the 2.5-5% banks are charging.
