The best way to make money is to merchant. You need probably at least 100k-1m+ to start. Merchanting is buying and selling items. I dont know what the best thing to merchant is at the moment because I quit because my pure got banned with all my money. (27m + items) I think a good thing to start merchanting is essence. Go to trading worlds and go to varrock east bank. If the prices are still the same, buy ess for around 25 each and sell for around 35 each. Thats a good way to merch until you have at least 1m+.
Pking is definately the funnest way to earn money. It may not be the the most profittable but at least it'll keep you busy. That's my way of making money.
