In December 2019, Poloniex waived all fees on Bitcoin (BTC) and USD Coin (USDC) trades, offering a significant opportunity for users to save money on transactions. This initiative followed a successful previous month where $500,000 was saved by waiving fees on USDC trades. The USDC stablecoin, launched in September, had rapidly gained adoption across more than 50 exchanges and platforms, with trading volumes exceeding 130 million. Circle, the company behind this initiative, aims to revolutionize financial transactions by making money movement more accessible and efficient worldwide. Users could convert USD to USDC through Circle's free service or via Coinbase, enabling them to trade BTC without incurring fees throughout December. Feedback was encouraged through Twitter or the Support Center, highlighting Circle's commitment to improving customer experiences and expanding economic opportunities.
