Somehow using VPN makes me feel safe while working with cryptocurrencies, like transactions, payments and buying bitcoins. I've been using surfshark vpn for almost 3 months now and I guess it's okay. I haven't really tried other VPN's though for I don't want to risk my wallet just to try other VPN.
I never use a VPN for cryptocurrency activities because the risk is great, no matter premium or free VPN because both can be a bridge for data theft on your device. Before it happens, avoid the risk of losing your assets.
