US people are buying LTC while the other world is avoiding it.
Although there's no source to this claim but if we're to assume It to be true then the rest of the world has to be smarter than US Investors. There's no good in litecoin, I don't see it adding any value to the industry. Litecoin is dead and just one of those projects enjoying the first mover advantage as without that they would had been lost gone like other newly created tokens.
The only scenario that'll pump litecoin is when every other old coins are pumping then in anticipation for litecoin to join the party, Investors will start buying. Litecoin on its own don't have any bullish news even their last halving event couldn't have any positive effect on the price. It only got pumped post halving but dump immediately afterwards.
