Yeah, shitcoins was great till they've fucked up the rates it's 6.5% on sell now and sometimes it goes well beyond that what they advertise.
Currently, if you do a simulation it's actually 7.3% on their website.
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).
But if I wanted to buy through shitcoins, (right now) I'd only pay a fee of 0.77%. I noticed that shitcoins tends to have better rates when selling when the BTC price is falling, and better rates when buying when the price is increasing.
