I took some exchanges with low fees from @eduBTCs list and here's my result:
XAPO: Damn KYC policy, they want to know the source and the amount of your annual income. Sorry, but that's a no go: https://themerkle.com/users-outrage-over-xapo-bitcoin-platforms-impractical-kyc-processes/
uquid: Seems to have cash flow problems, they sometimes can't even load your card because of missing funds. WTF!? https://bitcointalksearch.org/topic/bitcoin-debit-card-uquid-best-bitcoin-and-altcoins-debit-card-0-fee-deposit-1485950
CryptoPay: Fees are too high ... didn't look further.
SpectroCoin & AdvCash are looking promising at least I didn't find anything suspicious.
P.S.: I'm ready to leave @Wirex, your app isn't that good that I would pay like 5-9 % exchange rate difference
Update: Just read about scam accusations regarding SpectroCoin...forget them too :-D
