What is the most efficient and most profitable way to earn money in Runescape? -

I am currently LVL 95 and have squandered my money on useless items leaving me with a mere 300k in my bank. For those who have millions and millions, how have you earned this money? and what is a relatively quick, efficient, entertaining/fun and profitable way to go about earning millions of bucks? And no real world cash trading for coins thats just retarded... thankss!________My personal favorite way is ranging blue dragons, which are now often barren since the removal of bots. My recommendations is that you complete the Watchtower quest if you haven t already, and use the cave in the ogre town. This is host to many blue dragons with loads of cover spots to range from. Take a duel ring and telly to Castle Wars bank, then run back. This is fast, raises your range and prayer if you decide to keep the bones, and if you sell the hide and bones, is well over 4k a kill. If you camp out there for a while, you will undoubtedly be back on track with cash.________you could always buy a granite pl8 from barb assult for95k and sell it in g/e for 115k. keep repeating this and you will make alot of money. or you could spend all your money on steel bars and smith them into canon balls.(that only has a slight profit). wcing and fletching work. or just pick a bunch of flax.
