Keep in mind that if you swap houses that you bought as an investment, there is still the possibility of a tax liability. Barter is not excluded from taxation.
The first $250-500k of capital gains on houses is tax-free when you sell your house. I would argue that the IRS should treat cryptocurrency like other foreign currencies where the first $200 of capital gains is not taxed: https://www.irs.gov/publications/p525#en_US_2018_publink1000...
That would just put cryptocurrency on similar footing as any other currency.
