in that case vertcoin seems to be doing better job... also with gridseed and other better scrypt asics you can kiss litecoin and all other scrypts goodbye coz once asics take over scrypt you just end up with "duplicate sha256" and it loses its purpose all together as "asic-resistant, decentralized" coin... my bet is we're entering a new era of AI algos that are going to be intelligent and adapt to become even more ASIC resistant.. which is why i think gpu mining is going to be around for as long as decentralized mining is encouraged which is what makes cryptocurrencies attractive... also which blockchain is more secure? powered by centralized mining that can be taken offline with swat team or decentralized that'll be present in almost every corner of the world as long as there's internet...
No problem, altcoins are becoming more and more wortless.
I've been tracking the relative size of the BTC market cap to the market cap of all others at http://coinmarketcap.com/ for the past 6 weeks or so. In general the relative sizes have been stable (9-10% of total mineable market cap is non-bitcoin), but recently that jumped as high as 14% due to Auroracoin's supernova. That is subsiding but it remains the case that altcoins, by this measure, are growing - not shrinking. At least until Auroracoin declines to trivia.
In general I expect a few altcoins to emerge as winners with a superior feature set. They will then grow and ultimately supplant Bitcoin. In time you'll look at someone using bitcoin the same way you'd look at someone using Windows XP today. But that's probably a ways off, I admit.
