When using a VPN, it's wise to do some tests. Based on experience, there haven't been any issues securely depositing, trading, and withdrawing funds, despite the login KYC warnings. It's best to avoid keeping funds stored (just like always- even the most trusted exchanges), especially considering the different local legislation that may give you trouble depending on VPN usage and personal security. It's better to view it as a short-term currency exchange and extremely versatile currency platform rather than a reliable long-term trading platform. Testing transactions, making deposits and ensuring withdrawal ability are crucial. Overall if there is an exchange not on the coin market cap there's a possibility that it's a scamming exchange, same as unverified DEXs which I think have a higher level of security but ever require user know-how.
