For the "financial interest in any virtual currency" question on form 1040: in 2020 I bought and sold stock in the company Grayscale Bitcoin Trust ticker:GBTC ,which is a publicly traded company that buys and stores cryptocurrencies. Those transactions are stated on my 8949, and I paid capital gains tax on them.
So can I answer 'no' since GBTC is a stock and not a cryptocurrency?
