Can you pay with BTC or do you have to use their shitcoin for that?
On my main devices I'm using nostr:nprofile1qy2hwumn8ghj7un9d3shjtnddaehgu3wwp6kyqpq68euw93e4cam59llcmydav0akwjk2p4nfy3p85pn22xv9y2jxuzqf35lee through my private VPN on nostr:nprofile1qy2hwumn8ghj7un9d3shjtnddaehgu3wwp6kyqpqwr5azetlyy80apyxfp6y3eky3j54g0typwh3ceuftwvur4dmqjesuer6g2
But on my Desktop fedora box, I'm using Mysterium Darknet, a peer to peer VPN run and used by individuals.
I have provided several VPN exit nodes for a few years now earning $MYST, which I convert to USD.
The node earnings roughly cover each broadband lines cost.
Since the latest restrictions in the UK have come into force, I am now using MysteriumDark as a customer

I have connected to a random pleb in Japan, the same country as my Mullvad connections.
It's pretty decent and has after an hour and a half cost me 1/4 of a $MYST (about $0.05)

You can buy MYST with Bitcoin on the app, or you can swap stable coins on something like uniswap
