For some reason their fees fluctuate all the time. Right now, here in Poland I'm also seeing the highest fees ever, almost 7.2% if I wanted to sell through them (by comparison with
Flyingatom I'd pay a fee of 4%, still quite a lot but not as nasty).
It's the same in all places lately, I used a VPN (for some reason I can change to other currency on their website) and I got a 7.7% even in RON and GBP.
And in Poland, they advertise 6.5% right now, the reality is actually worse.
We had a discussion about them a few months ago and by that time I was only suspicious about their connections but still, the prices were great, but that's gone, the times when you could make a transaction with below 4% seem to be over. What's left is their no info needed and their enormous reserves in their machines, the one in Frankfurt has over 120k euros right now...
Probably it was just marketing to attract big players who care about the secrecy, with LB cash option gone, there is almost no option left for large amounts that involve close to zero risks.
