"Litecoin: silver pyrite to Bitcoin's gold"
"Litecoin:
silver carbon to Bitcoin's gold"
Well, geez, it's not quite that bad. I think the ratio for the price of an ounce of gold to an ounce of carbon is around 2700 to 1. Bitcoin to Litecoin value is only around 125 to 1. On the other hand, the analogy isn't terrible. Litecoin is basically a carbon copy of Bitcoin. And I guess you could also compare it to a lump of charcoal. It's still smoldering, but it will burn itself out before too long. Or take atmospheric carbon. Some people consider that to be pollution. Some might say that Litecoin is the equivalent of pollution in the cryptocurrency space. Heck, even your diamond comparison sort of works. After all, diamonds ARE a pretty poor currency (due to a lack of fungibility and divisibility).
(And by the way, dude. I'm just messing with you. I mean, I AM a Litecoin skeptic, but I wish it, and you, good luck.
