A substantial portion of the recent growth in our net revenues earned from cryptocurrency transactions is attributable to transactions in Dogecoin. If demand for transactions in Dogecoin declines and is not replaced by new demand for other cryptocurrencies available for trading on our platform, our business, financial condition and results of operations could be adversely affected.
For the three months ended March 31, 2021, 17% of our total revenue was derived from transaction-based revenues earned from cryptocurrency transactions, compared to 4% for the three months year ended December 31, 2020. While we currently support a portfolio of seven cryptocurrencies for trading, for the three months ended March 31, 2021, 34% of our cryptocurrency transaction-based revenue was attributable to transactions in Dogecoin, as compared to 4% for the three months ended December 31, 2020.
