If you are going to use VPN it may cause you a problem in the future the same as what happen to other traders before who use VPN and now suffer from verification or make their account freeze.

I think it would be better if you use VPS instead and buy a dedicated IP or residential IP. That way exchanges will detect you as a real user unlike on using a VPN that the IP gives you is always changes everytime you connect to VPN so it will gives you trouble in the future.
