Litecoin is actually much better for a professional miner. Why you ask?
Well the R&D cost for a
ASIC are about the same as for BTC. The production cost is higher beacause fast RAM is expensive.
ASIC will not be much faster than a high end AMD GPU ($ per kHs), but it will consume much less power. Because let's face it GPUs are pretty awesome at hashing, they're just not optimized for it. This means the difficulty will not skyrocket like it did with BTC. To increase the difficulty by a factor of 10, you need to add 1 million 7950 GPUs of hash power. Don't know about AMDs production capabilities, but a startup ASIC manufacturer will not get this kind of production capabilities anytime soon.
So when we get our
ASICs and if prices don't drop drasticaly, we can mine profitably for a couple of years. The next gen of ASICs will not be much faster, maybe 20-30% better, not 1000% like in BTC. So they won't make first gen obsolete, just less profitable. Also the first one to get the new tech will not make a fortune in the first month, they'll just make ROI 20-30% faster.
That's why an
ASIC is a much 'safer' investment IMHO.
