Well take an auto-Tab maker. They pull in around 600k/hour.
Lets say you manage to put in 10 hours of botting per day.
100000 / (10*600) = 16.6666
So you're looking at around 17 days of botting tele tabs to get 100mil.
Alternatively you could learn to script and have access to things such as Flight's Nature Rune Crafter which can pull in 900k/hour
100000 / (10*900) = 11.1111
So you manage to shave 5 days botting time off your cash aim.
Well there are lots of scripts(we have no bots here) that would achieve you. Monetary gain, just look throught the scripts section. A script that earns you 200k an hour will make you 20m in100 hours so in 500 hours you will have 100mil so we work this out with breaks that's 24 days, if you add another acc doing this than your making it in 12 a third acc to this and you have it in 8
This would be expensive IRL due to the new F2P trade restrictions.
Good luck botting!
