I use Bittrex to trade back and forth with altcoins to (try and) increase my BTC stash. Recently I noticed that my balance was lower then I would expect. I did some calculations and concluded that indeed, I was missing about 0.17 BTC. Opened a ticket with Bittrex and after a month of back-and-forth, they concluded that nothing is missing.
So either they are mistaken or I am mistaken with my calculations. Which may very well be the case. So if anyone could please give a second opinion, that would be much appreciated.
Attached a screenshot of my recent trades. No withdrawals (or deposits) were made during this time. On the 21 of July, I sold (practically) all my altcoins for in total 1.05574581 BTC (only 19 QNT was left unsold). After that I traded QNT -BTC back and forth, and made profits. If I sum up all my sells after the 21st of july, and all my buys, and subtract them from each other, I would then have calculated all my profits since then, right? I summarized those below. If I add that to what I had in BTC on the 21st of July, I should now a balance of 1.4247975 BTC. However my balance is only 1.249 BTC.
The 19 QNT I mentioned earlier was sold in this period for a total of 0,016403 BTC on the first of September.
So WTF is happening here. Where am I mistaken? Or is Bittrex mistaken?
BTW Bittrex send me some .csv which they said would allow me to self-audit, however those files were incomplete and the data could not be imported in Excel in a way that the data would be meaningful.
Any help would be much appreciated!!
