Risk Warning

Cryptocurrencies and their derivatives are innovative financial products with great volatility and high investment risks. Although fexwave is committed to providing users with easy-to-use trading tools, trading itself is still a highly sophisticated field. Trading digital assets and their derivatives are subject to high market risk and price volatility and may result in partial or total loss of account funds. You must carefully consider and exercise clear judgment to evaluate your financial situation and the aforementioned risks before using fexwave Services. You shall be responsible for all losses arising therefrom. If necessary, please consult relevant professionals to make informed decisions before investing. By accessing, downloading, using or clicking on “I agree” to accept any fexwave Services provided by fexwave, you agree that you have read, understood and accepted all of the terms and conditions stipulated in fexwave's Terms of Use as well as our Privacy Policy.

Trading by copying or replicating the trades of other traders involves a high level of risks, even when copying or replicating the top-performing traders.
