You are all treating these crypto currencies like stocks and commodities.
What gives them their value is that they are a currency.

I doubt any of these will actually thrive in the long term except bitcoin.
Litecoin especially won't,

They are simply being pulled along by the Bitcoin but in actuality is almost certainly a bubble. Why? With Bitcoin you can actually buy a large number of things, these other crypto currencies have yet to be used as a proper medium of exchange
