If by golden egg you imply it'll take me until retirement age to mine enough to matter - then yes that's true.
Well one popular speculative theory holds that the newish coins your mining with ltc will go up in value like btc once did. Idk. To me it's like comparing dimes and nickels, until nickels end up later on being used on someone's monopoly board as $20 chips, and dimes are used as housing sublet counters. No?
