The sale or other exchange of virtual currencies, or the use of virtual currencies to pay for goods or services, or holding virtual currencies as an investment, generally has tax consequences that could result in tax liability.
Thanks for sharing, I was not aware of such distinctions in how taxes are calculated and what someone can be taxed.
I remember reading somewhere that in real estate you can reinvest and you would not be taxed on it, up until you sell the property for fiat; cashing out.
Not sure if that's still applicable and why crypto would be exempt.
