Litecoin's decline after #LitecoinETF was most likely due to the "buy the rumor, sell the news" phenomenon, where investors sell after official news comes out. In addition, the still weak crypto market sentiment also contributed. Litecoin is also less attractive to institutions than Bitcoin or Ethereum, so the impact of ETFs is not as big as expected. Profit-taking by old investors who have already made profits could also depress the price. However, in the long term, ETFs can increase Litecoin adoption. However, price movements still depend on macroeconomic factors and overall crypto trends.
