there is no point in using a VPN, maybe today you are safe, but in the future, we do not know what will happen.. I only trade through the Firefox browser, indeed I have tried trading using a tor browser but the internet speed is very slow so that the buy or sell activity is very disturbed. So far I have no reason to use a VPN in trading..
It will just compromise the data and security of us. Maybe, it will help us today to evade some terms and regulations of the government. But it might also affect us just like what you said. If there is a legal sentiment between your country and exchange. And there are also restrictions, better not use vpn to risk what you have. In fact, there are many exchanges which not restricted your country to invest. Or try to fly away in your country in order to go out from the restrictions.
