VPS a waste of money? LO-FUCKING-L
Just run frost dragons? Are you kidding? I GUARANTEE I make more money than your frost dragon bot, on my VPS. No, I don't mine pure ess though.
It is VERY VERY unlikely that someone has more than 2 accounts (and even 1) that can even do frost dragons, and a lot of people don't have the computer to run more than 2 bots.
On top of that, is there even a premium frost dragon script? I don't believe there is, I think the only one is on RSBuddy. I, personally, would NEVER trust RSBuddy bots to run continuously without babysitting them.
VPS' are not a waste of money if you have half a brain. I have made over $500 so far in about 2 months.
