All trolling, noone answering on the question.
Yes, you can make pretty nice real money.
Farming only would not make you millionaire, indeed, but could give you nice montly income.
The scope per bot is very difficult to be predicted, depends of tons of factors, like banrate, daily income, finding the best price for the gained gold etc, and the time invested daily, to carry the bot.
Generally, you need more than gather bots to be able to achieve good montly income, having shufflers, ah bots and server analysis will help you alot!
Nowadays if you achieve montly rate of $200 per bot, you will be doing great, but even with $100 you will be pretty happy!
