I'd rather live in a world where Bitcoin became the dominant currency and Litecoin has died than in a world where Litecoin is still the #2 cryptocurrency but very few people use Bitcoin or Litecoin.
well tbh your diplomacy and not wanting to take on bitcoin headon has helped litecoin succeed relative to previous alts, however litecoin can and should take advantage of its 2nd place to bitcoin.
if litecoin stays a few steps behind bitcoin, it can avoid any trip-ups bitcoin makes and thus have an advantage, admittedly any terminal trip up by bitcoin, at this point in time, would likely spell the end for all existing cryptos.
while i think the idea behind bitcoin was a step in the right direction, i can't see it (or any other current cryptos) succeeding in any meaningful ways as a competitor to fiat.
though soon enough a alternative digital currency will come along that can, the only thing good to come out of the crypto scene todate is the 'idea'.
yes bitcoin will become a flavor of the day trading commodity (well really a pseudo fiat trading token), a few small time wall street players may pump it for a spin in time, so the into making fiat crowd here will have smiles soon enough.
