Although there are ETFs for Bitcoin and ETH, regulators are still very cautious about the cryptocurrency market in general. The approval of an ETF for Litecoin may face more difficulties due to concerns about price volatility, liquidity, and security.
Don't forget that ETH's ETF did not perform as expected, that is a recent lesson.
So what is the percentage chance of Litecoin having an ETF? It is 100% in the next 3 years but quite low this year (20-30%).
Compared to LTC, XRP and DOGE seem more promising. What do you think?
