there are plenty of ways to make money. Usually i start with getting all my skills up to 99 (non combat ones) and that usually gives u a good 700m. But if u don't wanna take all the time to do it, either use the agil tube, or mine rocks or even firemake. But the best way is to start wcing. From 50 till 99 cut maples and then at 99 cut regular trees cause you cut them instantly.

Hope you make lots of money

good job but stay active bro
