  Another mistake to avoid is not properly calculating the cost basis for each transaction. The cost basis is the original value of the cryptocurrency at the time of acquisition, and it's used to determine the capital gains or losses. Make sure to accurately calculate the cost basis for each transaction to avoid any discrepancies.
