Not sure if this is exactly what you had in mind, but I have one of these devices and it does what it says, albeit a tad slowly and you’re counting on the exit node owner to not be a POS if the man comes knockin.
I suppose if adoption of this became bigger, it’d become faster. In any case, it’s easy to setup and the hardware is easily portable. I use it as I travel for work and occasionally come across a hotel that’s blocking the usual suspect vpn services.
Since I so seldom use it, I don’t turm on the exit node from my hotel. Maybe would be diferently if i used it at home. Though I’m not entirely sure I’d be ok letting random traffic pass through me. I know, the hypocrisy runs thick. 🤪
But it’s a retty good idea. I think the crypto is a good reward, but also screams scam to others.
