Sure. 

Wanna know something else?  Your bitcoin is probably not going to be worth shit either, one day.  Same with every currency, it rises, falls, becomes obsolete, and dies.  What's important is selling your borgcoin for the next form of currency before it becomes worthless.

Of course altcoins won't beat bitcoin, that's why there called altcoins.  But you can still make money/btc off them, and that's why people use them.  Pretty sure 99% of altcoin users know that their coin isn't gonna 'beat' bitcoin, but they still make a profit using their alts in the short term.
