Bitcoin manipulation may be illegal if it includes fraudulent activities or violates securities laws. The legality is determined by the applicable legislation as well as the specific acts carried out. In the United States, the SEC has taken legal action against individuals and businesses involved in cryptocurrency fraud. Among the activities that have been targeted are spoofing and wash trading. Manipulating the Bitcoin price can affect investors, destabilize the market, and result in significant financial losses. It is, therefore, important that investors exercise caution and conduct extensive research before investing in cryptocurrencies.
