When I first started reading about Bitcoins / Litecoins the process of mining Gold and Silver is what came to mind. The reason gold / silver is used as a medium of exchange is there is a finite amount, which gives it intrinsic value. But what gives BTC / LTC value is not only can it not be inflated into infinity is that you have removed the human element from the money / currency equation(corruption, fraud, oppression, lying, cheating, counterfeiting etc). Basically your trusting a code that a machine processes to confirm that the transaction / coin is genuine. I've been around machines all my life, and machines will only do what you tell it them to do. If you set a protocol that you cannot change the machine will following that protocol until its conclusion. It will do nothing else, it does not think, act or even care about it's self existence. It just is.
The benefit in all of this is that it threatens the very institutions that hold a monopoly on power for the past 500 years. If this currency or type of currency can really bring them to their knees what's not to like? I got into gold and silver to "stick it to them" as well as preserve my wealth. But I also see that it is controlled. We all know that JPM games the silver markets. There's no way 20 something should justify the price for an ounce of silver when the supply is limited and is a dual purpose metal. Same goes for gold. So that really opened my eyes seeing as how they keep the price suppressed to the point that it does not threaten them. They can drop it whenever they want, and will continue to do so until they are damn good and ready to let it rise.
I still hold all of my metals, but I'm also venturing into LTC mining, while I wait for my BTC ASIC to show up at my door step to start mining them. It's an investment, and I don't invest more than what I am comfortable in losing.
