Thanks for that Topic link, I just read a few pages..my take in it is this:
If LTC will not change their algo, due to the large possibility of high-speed mainstream asics, they will accomplish a few things for themselves, ie, Network stability & security, obviously a large increase of mining difficulty, and it may just kill new Scrypt coins alot faster than they (new scrypt coins) are now. My reasoning for this is , that as these high-dollar ASICS are delivered and put online, end users will obviously be looking to ROI asap. They will initially mine LTC, and as any scrypt is introduced to the market that may show promise, they will mine that, to supplement their LTC endeavors. You may actually see them doing this with the 'IPO' coins more so than others, because they will have the ability, to essentially make Network difficulty levels skyrocket to essentially make it impossible for 'Joe the GPU Miner' to have any significant impact on 'IPO values', once on market, thus protecting their investments, as the coin in significant volumes will not me obtainable.
What this may mean for 'us' (N-Scrypt Miners) is that some of the 'Joe the GPU Miners' will indeed be looking for alternative algos such as N, X11, ect ect, or they may look the opposite direction, and choose to play the ASIC game, which may require a few things, A large 2nd investment to buy hardware & keep GPU's, or Sell current gear and go 'ALL IN' with asics, leaving them out of the 'Alt-Algo' game. With BTC in the shape it is now, the people whom took the most risk ie. buying hardware on credit & late to the mining craze , that NEED to pay their debts, may be the ones that will again take the most risk, looking for better ROI potential. Whatever happens, its going to weed out the people whom saw stars, and are now mining & dumping because they have to pay their mining bills.
I will close with the statement that, I'm by far any sort of expert on anything, and its just my perspective on how I think it may play out. YMMV
-Happily mining EXE
