I can verify, this works. I have done a transaction. The fees are high and their exchange rates are highly convoluted. BOTTOM LINE I put 90 usd in, and at the end of the process, in my wallet I had 0.0059btc. After converting back to USD (via calculator) that's roughly 10% of fees... If there's a cheaper way I'd like to know. That is ridiculous. (exhange rates of feb 19th 2018). some of those fees are flat rates and some are variable. mileage will vary.
