Or remote desktop. The advantage with teamviewer is if IP changes they can still log in with it.
I think you mean VPS and not VPN. VPN and VPS are 2 different things. Personally I dont see someone paying the 30 dollars mentioned per month unless its something they could not do on a legitimate VPS. I would watch traffic if you choose it.
I believe its linode that accepts btc possibly more. The thing is they do monitor activity. I would worry about anyone who would pay 30 btc for something they could get for less for regular money.
I do understand needing money. I would look into goods or services that your able to sell. On services one with less risk then allowing someone to use your pc, isp, etc for something that may not be legal.
