I think the same.
Altcoin to me is just a way to multiply my bitcoins, sometimes all my bitcoins are invested in a few altcoins but in the end i sell all of them for more bitcoins.
I think there is no competetion between them, it is just you have some alternatives if you have just enough capital then you can have the cheapest one. It is really true, we can sell altcoins to buy bitcoins.
