You're kidding, right? Anyone in the world, anywhere in the world, with as little as a couple hundred $ to invest can have their own mining rig set up and working for them. To invest in bitcoins you need nothing more than your own computer and an internet connection.
No that is not true. I have mined litecoins and bitcoins and many alt derivatives of such. The investing of present computer power is wasted. I also said new to bitcoins.
GPU's are out. Obsolete. Asics are throwing difficulty higher and faster than before when GPU's were all the rage. 22% jump in difficulty every 2 weeks is very hostile to any miner. Especially the emerging miner as I was.
Litecoin difficulty has only been tempered due to price of under 3.00. There is no place in which a new miner can fit in when old miners are in flux between bitcoin and Litecoin.
The alternate coin currencies get their value from Bitcoin. Alts are never worth mining unless you hold and you need to understand which to hold. Spending 200 dollars in electricity on a hunch that it will increase is not what I consider an investment.
Although I sound bitter I am not I'm giving my perspective on this whole idea. One I see very hostile to new comers.
