Thanks for the input. I'm not sure about the additional foreign transaction fees. It is something I will need to look into.
Regarding the fee - most of it really is the volatility / exchange rate between SBD and USD. While I expect I'll be able to find a more optimal exchange if I start doing this on a larger scale - I just did a test tonight with $30 SBD and it was around $25 USD by the time I got it actually cashed out.
Interesting. I do think you're onto a winning idea though
