Merchanting

Buy low, sell high.

That's the just of all successful money making.

Not much to it. Buy low sell high, and only merch things that are popular and desireable. And i hope you have a lotttttttttttt of patience.

You mean the opposite, right?

yes if you don't have patience you will never be able to do this that is why i just can't do it

Low-end minis may be a good place to start off.

From what I have seen I would try going after armbraces and/or tormented gems to make gold...

Agreed. Buy mini's for 10k or something like that and sell them for 5k higher, etc.

Bad idea, you haven't made enough money to get to that point and since the armbrace market is a bit unstable and decreasing, as soon as you buy one it could drop the very next day. (not to mention they are 100k+15e). Gems aren't great to sell, practically no one is buying them anymore and you want something that is easier to sell. I would definitely suggest farming the elona free chests, if you have nightfall. Trust me, if you build up more, you might be able to make a nice hefty sum of money when you power sell, instead of very measly sum at 100k, you will at max get maybe 100k more in the next months or two.

Also, remember to check the forums on price checking, there are a lot of noobs who find good stuff and sell for a very cheap price. If you find something for a potential profit, get onto guildwarsguru FAST check the PC forum for the stickies. If you see you can sell for a 10k profit buy it fast then port and sell to someone in Kamadan or L.A. (these two places are the only good places to buy/sell anymore) or come on here.

Or try crafting and selling Consumables if you have GW:EN
Trading minis is a good suggestion as well.

But the first step you will have to do is:
Watch the market and Know the prices
