Alt systems are just acting as a ponzi, all dumb money.
If anything forks will be created within Bitcoin itself to solve an issue people aren't sure of.
So you say you had 3000 LTC, meaning you made a mistake selling them before they appreciated. Why would anyone believe you then and what exactly do you know since you didn't know to keep your LTCs and sold too early? LTC seems to be doing fine, is it because you sold too early and now biting your elbows for that you wish death for alt-coins? They wouldn't care about that, they'll keep surviving and diluting bitcoin value. Because technically they are equal to bitcoin, they only lack in infrastructure, but that's just a matter of time. Not all alt-coins will survive, only those that have serious devs and community behind them, but for sure bitcoin won't be the only game in town.
This goes back to the ponzi effect.
Litecoin has no other purpose but to store fictional value until it is depleted and taken over by the most powerful currency system in which will be Bitcoin or government money.
Multiple currencies cannot continue to exist, or stability issues will continue to arise within all value systems.
