Thank you for clarifying things with SEPA in DM, kudos for your patience and instant response.
I use Ownr wallet for $ETH and $DOGE currently. No much difference from any other wallet, so I guess you should attract ppl by some unprecedented features or by gaining more trust (ie getting more public). The best option would be doing the both

I can't say that bitfinex is the best partner for ownr , but, anyways, their collaboration make some hype. Hopefully you got lots of new users from it, guys.
