I don't care what people say, no crypto-currency is safe from ASIC chips. When a cryptocurrency becomes valuable enough, ASIC chips will be made.
I can't agree more. Although Litecoin was designed to be
resistant to ASIC design, Scrypt (as best I understand) was a cryptographic tool designed specifically to be expensive to design and build ASIC devices to target it. The inventors of scrypt never claimed it to be ASIC-proof, they claimed it to be ASIC-cost-resistant. The designers of Litecoin were probably more aware of that than anyone. there's great technical explanation of scrypt as a crypto-tool with regards to ASIC design cost here[1].
In my opinion, it is still serving the same purpose even if scrypt-ASIC devices are coming to market. These devices are going to be more expensive to design and manufacture, and are yet to be seen to have the exponential performance increases over GPU miners that SHA256 ASIC's have shown. Even if they do increase performance by orders of magnitude, they will do so at the cost of a boat-load of RAM and memory throughput, which is neither easy or cheap. This will slow the flow of ASIC's in comparison to the btc counterparts, and things would stay decentralized longer.
If people can make money with a raw computing process, people will build computers to do it faster.
The other differences between litecoin and bitcoin are pretty solid: transactions should happen faster, and there should be more total available to mine (The recent price spike seems to tell me that pretty clearly.)
When BTC touched the price of an oz. of gold, the need for a "silver" along side got a whole lot more tangible. lol, forgot to mention that ltc is worth more than silver right now, I didn't realize until this very moment.
