Indeed, the CryptoTab VPN belongs to the owner of CryptoTab Browser. I wondered why to offer VPN for free for 5 years?I've never even heard of CryptoTab, so obviously I'd recommend AdGuard VPN. CryptoTab seems to be related to some web browser that mines cryptocurrency, which seems kinda lame to me, IMO.
What exactly? I could not find anything specifically from their homepage.something
