If you look at the coinmarketcap, although the LTC price is low than the ETH price. But I choose to invest in ETH for long-term investment. Because the development of ETH is getting more attention and ETH is always the best Altcoins for investors to choose an investment.
for the sake of safety, ETH is indeed the best because the quality is good so it is difficult to get down very low but because of that the price of ETH tends to be more stable so if I want a big profit I think LTC is a good choice.
