The other big method to dump lots of resources into bitcoins is with 'bitcoin mining'. Google it, as there are tons of info on it. Be prepared to spend $1200+ per 'rig'/pc to mine. They use multiple high end GPU's to power the mining, and get a fractional part of a btc in return. They consume lots of electricity and need to be running all the time. You could use regular PC's, but use a 'bitcoin mining calculator' to see if it's worth it.
Then be prepared to have traders that will manipulate the orders to their advantage, in a highly volatile market, when you try to cash out. There are tons of scams out there, but there is bunches of free info here in BBHF. I've been studying it on and off, for a few months, and am holding off until the middle of February. That's when eBay and Overstock.com will start using BTC. eBay just announced they will allow BTC sales in their UK classified arena, but if it goes well, I'd imagine that will overflow into their regular business. I'm not too sure what Overstock will be doing, as I didn't pay too much attention to that announcement. Looks like it may be starting to come into the mainstream, but it may be too early to tell.
Hope this helps, and +5 to Ruscat for the good info on bitcoin gambling. RusCat, care to share the name of that website you mentioned? PM it to me if you don't mind...
All the best, and good luck in your BTC prospecting. BigDaddio
