LTC has some features that make it far better than bitcoin so I personally think we should see it go up!
What's your take on Litecoin?
Eventually yeah, some of the most reputable coins will go down and some even die. As new and improved coins with new features come out older models become obsolete. Just like model T!
So, in this approach we might simply say that Bitcoin will eventually be overtaken by another yet superior crypto.
Coins with older tech, and critically, no threshold network effect, will be supplanted by newer coins. I think that's likely to be Litecoin's long-term fate.
Bitcoin is the only coin that has arguably achieved enough network effect to be have its ledger-state survive whatever evolutions may happen in cryptocurrency over the years.
