Depends on how many RAM the VPS has. It takes 500 MB for one bot to be running. So let's say you have 2.5 GB worth of RAM; you would be able to run 5 bots.
Well if I wanted to run say 4 kminer bots on 1 vps, wouldn't I have to open 4 separate clients? Or can I bot 4 mining accounts on 1 client with 1 auth?
I already have a method for running one auth on the same client on different tabs. But, this method still hasn't been leaked and is being sold on several black market sites.
