I have owned Kore since the start. Back when the original dev was still involved and abandoned the project. MikeMike stepped in, invested his own money and saved the project. Re: bittrex - they are simply overwhelmed with recent verification requirement changes and btc forks. Patience with Kore is rewarded.
I don't think anyone is doubting how long it takes for Bittrex to get things sorted, Its more to do with how long its taken the team to get this new wallet fixed. The longer it takes the more it feels like there are far more fundamental issues with it. I still have not sold one coin yet during all this. But, the longer this goes on, the more nervous I, and I am sure others are getting.
