Investing!? Runescape How to?

Okay Investing is hard at first but have enough money like this example Ex. you buy nats with 60+ mill then you around 210k of them so now they rise let's say 2 gp you make 400k without even logging! This is easy i say and then you got how too check what is rising go too this linkRunescape Exchange Great isn't it! Just type in what item you want too buy and then you got it. I hope you are doing good. My times of things happening. Once i bought a santa after losing like 500k i sold it being mad then the next day it raise 700k and then kept raising for another 2mill mad isn't it! My big tip is too look for something and check if it dropped a lot and then buy (but has too be something everyone uses like runes or axes or weapons)
