I presume the supply of GPUs is not constrained. Thus the difficulty for the GPU coins will always rise to match the price. Thus GPU mining won't be exceptionally profitable, especially for the marginal profit miners.
But the entire point I've been making is that the supply of Litecoin ASICs is very constrained. The newest most efficient models are sold out and the other less efficient A4s are limited to old stock.
So this means that the difficulty (hashrate) for Litecoin will not rise commensurately with the price, and thus those miners who choose to buy Litecoin ASICs will be making a fortune if SegWit is activated (or the market believes it will be activated). This is a very unique advantage for Litecoin because it is the only coin that has an ASIC and is incredibly undervalued!!!People are so slow-minded. I have to explain to them like ABCs. Hehe. No offense but I had already implied that in my posts 2 days ago. But most people can't figure out what I mean unless I carefully explain it. No problem I know that people need more explanation before they will "get it".
Economics is complex. Sometimes I would rather just think and not have to explain because my brain moves much faster than my fingers can type.

Thanks for explaining it too me you really helped a lot. Also sorry too, no offense but I have not read your post 2 days ago that implies what you are explaining to me in the post quoted above since I am not reading that much when I open a thread, I am just reading the original post and also the recent posts. I agree with you though that economics really is complex and somewhat hard to understand so it needs to be explained before people get it.
