another way to make money with a good profit is to buy iron ore go to falador and smelt it then bank and repeat till its finished and then sell this way has its flaws but you will get you’re money back and more

also one more is to get you’re mining level really up and go mine runite ore but its also dangerous because its in el 40 in wild sure you wont get attacked by other people but you might get attacked by monsters

the other way is go to karamja and fish lobsters this way is really good because lobsters are both good food and good money
