Specially If You are Country Where the laws not Crypto trader Friendly?
Do You hold Ur machine or wallet in better juridical locations?
If you are in a region where accessing crypto-related websites e.g exchanges or trading platform, is heavily restricted, you have no choice but to use VPN or to use a proxy address.
But as much as possible, if you are free to access such websites in your region, don't make things complicated and don't use VPN for such as a reason that you want to hide your IP or something along those lines as it might give you tons of problems with the exchanges.
Anyways, to give you a much better response, what's the reason you ask for this?
