Has anyone ever wired money internationally using TransferWise or a site like it?
It would be so much cheaper using a site like this than transferring through a bank, but as I don’t know anyone who has tried it, I’m a bit wary. Would love to hear from people who have used a site like this before. Thanks! 
I haven’t used them, but they are reputable. I don’t think they work in or out of Taiwan, though.
Yeah, unfortunately I have just discovered that the set of currencies they work with is fairly limited. I’m now looking at CurrencyFair instead (they don’t exchange TWD, but they do exchange in UAE dirhams, which is what I would need it for).
