Eidoo wallet compatible with iBTC (all ERC20 tokens).
https://eidoo.io/I am using this mobile wallet for saving my ERC20 tokens.
It is an easy to use wallet after setup. You can connect it with the Etherdelta exchange.
For retrieving the private key (for usage on Etherdelta) of your personal Eidoo wallet read below steps:

If Eidoo wallet is not recognizing your iBTC tokens (cq. unknown) just use the following steps;
Click on IBTC, press the info button top right, change name IBTC to iBTC (small i). The rest should be correct (symbol, decimal, market).
Click save and you will see it is recognized by Eidoo at that time. They are building an option into the app so in future you can do exchange within the app.
Hope I informed you sufficiently and good luck.
