It is asking if you were given any crypto currency or if you bought and sold any. Given is a gift that would be taxable at rate you got it. You bought and sold it would be cost difference to determine loss or gain which you would pay taxes on
The question actually says: "At any time during 2021, did you receive, sell, exchange, or otherwise dispose of any financial interest in any virtual currency?"
What makes it confusing is that it does NOT say PURCHASED or BOUGHT.
From www.findlaw.com: "If all you did in 2021 was buy cryptocurrency with U.S. dollars, you will not be on the hook for anything." It goes on to say: "Thomson Reuters tax consultant Shaun Hunley says that "you can check 'no' on that question," if all you did was buy and hold crypto."
The terms "Purchased or Bought" are purposely excluded from the question.
If you purchased. or bought cryptocurrency it is not a taxable event, and if that was the only circumstance you would answer NO.
However, if you "receive, sell, exchange, or otherwise dispose of any financial interest in any virtual currency?" it is a taxable event and you will answer YES.
("Receive" can refer to shares gathered from an airdrop or staking)
