[TF2] I just bought a Strange Machina!

Anyone who knows or cares about TF2 trading, a Strange Machina is worth about 15 keys (about 37 USD), and I just traded for one! All of the keys I traded were pure profit, I started trading 2 weeks ago with only the in-game weapons that I acquired as drops, and went from 1/2 key in value to almost 15. I bought my Machina for a lower price, and since the crate that drops it has been discontinued, it's price is rising. If I ever decide to sell, it'll be great profit. But oh dear god, is it fantastic. A few weeks ago, I saw a guy who had one on a server, and that was what inspired me to start trading for myself. I wanted it, that was my goal. And now...I feel fucking accomplished as hell.

TF2 trading is ridiculous. I sold a virtual hat for 100 dollars. I could have gotten way more too if I was more patient.

That was a while ago and I stopped trading once the value of metal plummeted to the point to where it was worth nothing, so I'm not sure what its like these days.
