It seems that scrypt(1) is always used as PoW, when a cryptocurrency mentions it uses scrypt people naturally assume that the difficulty adjusts through the coin taking advantage of scrypt key-stretching, in reality scrypt introduces little to no advantages and a significant downfall by it being a relatively new algorithm.
Isn't it ultimately misleading people since scrypt using currencies will always use 128kb of memory and in all reality will never be GPU or ASIC proof?
Very few Scrypt coins will servive if ASICs do come out. We'll see more hybrids or unique algorithms, with one becoming popular for being ASIC resistent.
