Hello KontPont,

Exchange fees are approximately 2-4% depending on the crypto exchanged and market condition however we do not publish this or make a guarantee of this range because the market condition is always changing. Since we cannot have fixed rates, all fees are built into the amount received when using the conversion preview tool, at https://my.xbtfx.io/en/exchange ,  so there is no unexpected result when exchanging coins with us.

Regards,
XBTFX
