VPN is good , the best choice if your country ban crypto, but be careful I think You should use paid VPN ,not free.
I also used VPN , and safe
Yeah I also used VPN to do trading in exchange, But not often.
Because crypto didn't being blocked in my country.
Maybe at the country that block crypto and exchange, teh citizens can use VPN or proxy.
Always be careful with free VPN.
Because It's about asset on your exchange account
