Well this is just peachy!

Not a problem to me though. I've mined all my bitcoin/litecoin/etc since 2013 and have nice CPA and IRS Tax Forms as a business to show such.
Then again if they do apply capital gains like land for EVERY transaction of BTC and or other crypto you were supposed to keep track of....I too am 'verily' screwed.
(ie you bought 1 btc at beginning of the year and paid for something at the end of this year and now have to pay IRS capital gains of 20% on that 50 bucks you made)
Well, then I too am screwed, if the fishing expedition in the above link pops that far.....ease of compliance has never been a good excuse for IRS noncompliance don't ya know.
Please take the poll on your odds on how likely even some of the above may be.
