An exchanger is required for trading and I have noticed that gambling sites are restricted for different countries, which means that the website cannot be accessed without a VPN from that country.  But this is not the case with Exchanger, Exchanger supports all countries and can be accessed very well without any kind of VPN.  So why should we use VPN for trading? On the other hand there are now many decentralized exchange DEXs for trading which cannot be controlled by any country's government.  So I think there is no need to use VPN in this case
