They are ignorant of the fact that Bitcoin and Litecoin are payment systems (which happen to have their own currencies). The more people that lose sight of this fact, the more likely it is that Bitcoin (and Litecoin) will fail.
I think utility and speculation are intertwined and both necessary for the coins' survival.
Agreed, but viable speculation only happens with something that has long term potential and that's where utility comes in.
Bitcoin and Litecoin have essentially the same utility. Its mainly a 'first mover' aspect for Bitcoin to be ahead. People like choice, also if it doesnt differ that much (look at cars). If LTC can get some basic application, it will thrive if Bitcoin wins big.
Higher risk, higher reward.
