I don't think the liquidity of currencies will be affected / everyone will exchange USDT for USDC and everything will remain as it is

In an unprecedented decision, the European Union announced the delisting of Tether (USDT) from all European exchanges by December 30, 2024, under the MiCA regulations that require stablecoins to obtain an electronic money license to operate in the Union. This decision will lead to a decline in liquidity in European cryptocurrency markets, as Tether is one of the main stablecoins for providing liquidity. Experts expect that this will cause a large portion of trading to move to other markets such as the United States and Asia, which have more lenient regulations. The decision may strengthen the position of other stablecoins such as USDC and DAI, which may replace Tether on European exchanges. However, some believe that this decision will lead to greater volatility in cryptocurrency prices at first, and pose a major challenge to European platforms. At the same time, the European Union believes that this move will contribute to creating a safer environment for investors and enhance confidence in the market in the long term. The decision comes at a sensitive time after major market crises, such as the collapse of the FTX exchange, and aims to regulate cryptocurrency markets more strictly and reduce opaque activities.
