I try hard to buy some bitcons but things seem way too obscure to proceed with anything.
My case:
I've created a wallet at Blockchain.info. I connected it to my bank acount A. Trying to proceed via my bank I realized that my bank charges very high rates for the transfer (7 EUR for a transaction of 15 EUR!)
I tried to add, or at least change my bank acount in my Blockchain wallet, but I didn't find such an option(!) So, I've create a different wallet as everybody says "you can have as many wallets as you like".
I got succesfully through the coinify identification (I re-sent my documents) and now, trying to proceed with buying bitcoins in this second wallet, my bank acount seems... already set up, too, without me doing any such thing in this second wallet. I suppose Coinify or Blockchain (I cannot tell the difference, yet another obscurance) automatically connected my bank acount A to this second wallet, when the whole point of me creating it was to connect it to bank acount B.
What a labirynth...
I have a few information’s about coinify so I can’t help you.
I recommended you to start using segwit wallet.
