Is it illegal to use a VPN for crypto trading?

Good day, I'm curious about the legality of using a VPN for cryptocurrency trading. I've heard that some traders use VPNs to bypass restrictions and access exchanges that may not be available in their region. However, I'm not sure if this practice is considered illegal or not. Could you please clarify the legal status of using a VPN for crypto trading? Is it considered a violation of any laws or regulations? Thank you for your time and assistance.
