A better analogy would be: Bitcoin is like Coca-Cola and altcoins are like wannabe-colas
They promise new and improved flavors but eventually fizzle out when costumers realize they are nothing but cheap imitations of the original thing
Litecoin seems to be the Pepsi so far

LTC is basically coke zero. A watered down version that is much shittier. Of all alts, LTC literally has the least features possible
