At risk of sounding sale pitch'y. Mullvad is the only VPN the longer I use the more I like it. I've tried MANY competitors first and all the other ones so far seem to only get worse over time.
I love that I can pay directly with a crypto wallet and have true anonymity.
I do really wish they still provided port forwarding, I understand why they don't but that was really useful and the only competitors that seem to don't exactly seem trustworthy to me.
That depends how you obtained the crypto in the first place.
In any case, its certainly better than visa, but if you dont trust your vpn provider the real issue is they have your IP address and at best just a pinky-promise they dont log.
I went in on Monero (which Mullvad accepts for now...)the only early crypto that had a viable usage plan from the beginning. That was of course before I realized that crypto would of course just be turned into a massive scam wheelhouse and any coin with real utility value to challenge fiat currency would of course be regulated against. (not salt its still worth a lot)
I am aware most crypto is not anon without extra effort.
