Crypto trade loss write off

[RosieD]

What documentation is needed to write off a trade loss? If the loss was substantial would only $3000 of that be written off towards income? 2nd scenario, if there was a gain (say home sale profit) and the trade loss. Would the trade loss offset the capital gains of the home sale?

You would report the sale of the Crypto like you would report the sale of any security.  On your Schedule D.  You are correct that you can deduct a $3,000.00 loss, providing there are no other gains, per year until the balance is used up.  

As far as the gain from the sale of a house, you didn't specify if it was a your primary residence or a rental property.  Rental property would be a capital gain and would be offset by any capital loss.  Personal property would be an ordinary gain.  Thus, it won't be offset by any capital loss.
