Is Bittrex reporting to IRS?

Excuse me, could you please clarify whether Bittrex, the popular cryptocurrency exchange platform, is actively reporting their users' transactions to the Internal Revenue Service (IRS) of the United States? This question arises from concerns over tax compliance for individuals and businesses engaged in crypto trading and the need for transparency in financial transactions. Does Bittrex have any official policies or procedures in place to ensure compliance with IRS regulations? Thank you for your attention to this matter.
