Okay, if I wanted to create a EOS wallet with Ownr, what should I do first?
They have not yet supported EOS.
This is all they have so far:
BTC, BCH, DASH, ETH and LTC.
If you want to use their wallet. Applications are available for both desktop (Mac OS, Windows and Linux) and mobile (iOS and Android).
You will find download links in OP and on their website.
