Same, and it made me decide I wouldn't deal with cryptocurrencies until this stuff has proper infrastructure around it. It was such a pain in the behind to write scripts to reconcile all the weirdly formatted transactions and movements across exchanges. I'm not even sure it worked out properly in the end, but after spending 5 days doing it, I decided what I got was probably close enough to the truth, and I called it day. If the IRS is ever unhappy about it, I wish them good luck figuring out the actual number. I'll happily pay the penalty if they make the calculation for me and save me the trouble!
