Good way of making money or gp on runescape ?

what is a good way of making money or gp on runescape ?

I used to play a looong time ago and the way I made money was get your fishing lvl to 50 ( doesnt take long, fish xp goes up quick) and go to karamja island and catch an inventory full of swordfish go to bank in draynor village and keep repeating...sell 100 swordies at the grand exchange and you have around 50k

I make money by mining and fishing. I recommend fishing since you gain levels quicker than mining. but if you get 60 mining I recommend joining the mining business. if you want you can add me -inuyashasng-

kill a lot of cockroach drones until you get limpwort roots and then buy red spider eggs or get them at karajama volcano and then ake them into strngth potions
