Some pertinent information regarding the US Tax Code

Q-7: What type of gain or loss does a taxpayer realize on the sale or exchange of
virtual currency?
A-7: The character of the gain or loss generally depends on whether the virtual
currency is a capital asset in the hands of the taxpayer. A taxpayer generally realizes
capital gain or loss on the sale or exchange of virtual currency that is a capital asset in
the hands of the taxpayer. For example, stocks, bonds, and other investment property
are generally capital assets. A taxpayer generally realizes ordinary gain or loss on the
sale or exchange of virtual currency that is not a capital asset in the hands of the
taxpayer. Inventory and other property held mainly for sale to customers in a trade or
business are examples of property that is not a capital asset. See Publication 544 for
more information about capital assets and the character of gain or loss.
Q-8: Does a taxpayer who “mines” virtual currency (for example, uses computer
resources to validate Bitcoin transactions and maintain the public Bitcoin
transaction ledger) realize gross income upon receipt of the virtual currency
resulting from those activities?
A-8: Yes, when a taxpayer successfully “mines” virtual currency, the fair market value
of the virtual currency as of the date of receipt is includible in gross income. See
Publication 525, Taxable and Nontaxable Income, for more information on taxable
income.
Thank you for this information. Even though I'm not a novice user, I'm really useful. Sometimes it is really worth remembering some of the things that may later turn out to be important.
