Okay, this is my first thread that I've posted here so please forgive and minimize the flameage.
First of all, I realize this may seem like common sense, but really, how many people actually use common sense?
1: ) Be a miner, skill level doesn't matter as long as you are able to smelt Titansteel from Titanium Bars (x3), Eternal Earth (x1), Eternal Fire (x1), and Eternal Shadow (x1)
2: ) Instead of using your Titansteel cooldown for your own selfish needs, why not sell it to someone who could need it more?Sell your CD for X amount. (It can sell up to 45-50g on my server.)
3: ) Next, BUY someone else' CD for anywhere below what you sold yours for.
4: ) ??????
5: ) Profit.
The point of this post is to, rather than getting an approximate profit of let's say 100g from simply selling your Titansteel, you're now getting 100g PLUS the difference in price between the cooldown you bought, and the cooldown you sold. Yes, a minor profit difference it is, but when you're dealing with money, every little bit counts!
Edit: I suppose if possible, you could buy two/three/etc. cooldowns and if you're staying under your (Apparently relatively high) sold cooldown price, then you're still not losing any potential money, and therefore recieving straight profit.
