Well I am stupid like a broken brick. I proclaimed myself as 'IT security enthusiast' and what I did in my first transfer from bittrex? Put my public memo key in memo field. And it was after I've read posts of @lukmarcus and @noisy about not doing it. What a moron. I have planed a self-sterilization for this evening so no more chances for my genes to survive. And all of these greatly explains my avatar image selection (this sentence is kind of offending for apes, sorry guys, didn't mean to).
It is not helping my despair that it was only public key. No keys means no keys.
Sending public key doesn't make any harm, it's just an indicator that you are doing something wrong which might lead to some bigger mistakes in the future. Fortunately you've realized that on time and now it's good.
So... nie ma tego złego co by na dobre nie wyszło ;-)
