Damn, I've been playing on a lot of these sites using the internal exchange functions and didn't know that the rates are actually so bad.
Thanks for the heads up, OP.
I've probably lost around $100 just to fees alone. And this is easily avoided if I had just used any other instant exchangers that give much better rates.
That is the fee for your convenience, hope you realized ot very earlier because many people don't even know such things for years and if they did they might be saved few thousand dollars.
