I have a old Ninki Wallet bitcoin wallet which I used back in septeber 2015 on my iPhone and left it there with the phone. I have a little bit over 4 Bitcoins on that account but sadly yesterday when I checked the old accounts it seems that the service shut down.
I tried to use the ninki-wallet tool from their github with all the proper data (offline key, online key, private key) but without success, it just seems to forever get stuck at Step 4 with the message "Checking for xxxxx address". Also I tried to analyze the background data the recovery application uses and it seems that when it runs these messages appear:
For each and every single address it says it's checking this is happening. Therefore, anyone who thinks I can solve this or can recover it for me (trusted members, of course), I am willing to give 10% of the bitcoin amount on the wallet for this.
