Given the stability of bots at the moment, I recommend neither (as a previous user has suggested)
On the other hand, no one wants to hear that, so I recommend going with the computer. As long as you have the internet connection to back it up (shouldn't be very difficult, as it doesn't require THAT much bandwith to play) a decent (and still inexpensive) computer WILL hold its value (and likely you will gain far more use out of it) far better than renting a few vps's.
My reasoning behind this is as follows:
1. Most mass bot-farms fail. Cold, hard, fact. If they didn't, everyone would be doing it... easy cash right?
2. If the bots go down, you're screwed. If you have the computer, their are multiple other ways of monetizing it.
3. If you haven't already figured this out - running 10+ bots is not nearly as easy as it may seem. While I do not know what bots you plan on monetizing, I do know that constant hours of a)fixing bot problems b)selling the gold c)maintaining everything in the meantime - can be rather stressful/difficult to keep up.
If you have the computer, think of it as more of a longterm investment. Far less of a chance of you being stuff with something that you can't use, which in my eyes, is the worst possible outcome.
Anyone disagree? I love debates
