Do you use VPN proxy?
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're using an exchange I don't think a vpn is needed. Because in every country where crypto exchanges are used, no VPN is required, they can easily trade without VPN. However, I have seen many times that there are some exchanges which are not open due to network problems but can be accessed very easily if VPN is enabled. But to my knowledge there are no crypto exchanges that require a vpn to access. You can trade any exchange without VPN if there is no VPN required to access the exchanges in every country.
well, maybe some countries banned some popular exchanges, so they use VPN to access them. However, this is very rarely the case, besides nowadays it is quite easy to access popular exchanges, and in fact almost every country has their own trusted exchange. Personally, I have never used a VPN to trade either. Until now, almost all popular and local exchanges can still be accessed without obstacles.
