U.S Tax Law and the Blocks I earn on BlockGeeks

Hello, all New Blockgeek developer Apprentice here,

  I learned today that the IRS is sending out letters on the tax treatment of cryptocurrency; I want to educate myself before the IRS educates me or penalizes me for my ignorance!

   So, for tax compliance, what is the exchange rate of my Blocks to dollars?

  thank you and Cheers!
