And Bitcoin is far from being "the one & only trusted ledger." Litecoin, Peercoin, and Primecoin have been doing very well for a couple of years, TYVM. Why would you only trust only one form of proof of work? If a SHA256 or ECDSA exploit is found, BTC goes to zero.
What's so funny? Being smug isn't an argument, just an admission of ignorance.
LTC in particular is punching far above its weight class in terms of market cap vs volume:
Bitcoin $ 4,916,312,384 $ 11,867,000
Litecoin $ 121,242,367 $ 1,628,240
I see you are a newb who just registered this year, so you can't be expected to remember LTC went to the moon last time BTC suffered a bit of technical difficulty in the form of a chain fork.
There is no silver to BTC, no copper, no aluminum.
There is only one.
