(Runescape) How can I make money fastest with my skills? My user is Flarezing (To view stats).?

Do frost dragons, but go on foreign worlds while you do. Everything you read will be in German, so just use pictures, but there are usually 100-700 people on those worlds. Go to the bottom right corner of the Runescape homepage and click the flag with the black, yellow, and red stripes. I can't go to frost dragons but for Yaks, and Blue Dragons i go on those worlds and there's usually 0-2 people, so it should work with frost dragons.
