First evaluation of NoblePay (app for Android):
211 ERC * 0.00005295 BTC/ERC (bid on bittrex) = 0.01117245 BTC
0.01117245 BTC * 715 USD/BTC (bittrex) = 7.98830175 USD
1 USD = 0,921879897 EUR
0.01117245 BTC = 7.98830175 USD * 0.921879897 EUR/USD = 7.364254794 EUR
Noblepay asks 210.94089236 ERC for 10 EUR in SEPA transfer (European bank transfer).
That's a 2.635745206 EUR markup for the service. Not too bad for a start, considering the fact that NoblePay is operated by a business from Australia.
I haven't tried the actual transfer yet... but I might do it towards the end of the month...
