I went through the same thing with my WAX account when I was making hundreds of dollars per day from my play to earn games like RPlanet and Alien Worlds. It would have been virtually impossible to track it all. That's when I decided I was just going to claim what I converted to fiat. I made sure to bake in whatever I was going to owe for taxes so I wouldn't have that extra burden. What I didn't plan for was the penalty I had to deduct for in the following year. I ended up getting that money back because I didn't take any gains the next year, but it was still a lot of money to tuck away at the time.
