I think that when BTC are taken over by Asics, people with GPUs will move to Litecoins, and when that happens, they will begin to enjoy litecoins more and litecoins will slowly become more popular with the miners versus bitcoins, which I think will make Litecoins more popular overall. Then when someone figures out how to make an Asic equivalent for Litecoins, a new currency will do the same and so on.
I agree with this. This is also why I chose LTC over BTC to mine.
I am glad that you cannot mine LTC with ASIC and I am going to build up a nice GPU farm for LTC.
This whole digital currency thing is SO much fun. I love it!!!
