If I calculate correctly I have to pay around 10€ fee if i only want to transfer around 40€?! Is this normal, I mean its 20% of my transaction value The last time I thought it was less...
Edit: I think i got it, I can lower the fee, but then the conformation is not so fast !
That fee is normal when you collect a lot of little payments as I already explained. These results in a lot of spending inputs therefore increasing the size of you transaction. Based on bitcoinfees21 website the cheapest recommended fee is 480 satoshi/byte so yes that is normal when you have a lot of spending inputs.
Next time try to withdraw only big amounts of 0.025 and up in bitcoin and you will be sure you will be pay a cheaper fee.
Glad that I helped.
