I've bought with the peakd embedded thing. It works fine, give it about five to ten minutes before you panic, because it will go through, then you will see or hear nothing, receive no indication its gonna happen after the last screen indicating you are done, but it does come eventually.

Going out, as noted above in other comments, you can go out through hive engine swapping to LTC (litecoin - usually the fastest/cheapest combo in the USA to coinbase for me) and you'll eat fees at hive engine, then at coinbase to swap the ltc to whatever else to hold, trade or withdraw, then the withdrawal fee.

These fees - as all usually do - scale with your amounts to whatever limits they peak at on these steps along the way.

So yeah, I do it because its the only way, but its not so cheap.
