Namecoin may be the first altcoin, but Litecoin was the first well-known altcoin until Ethereum came along.
Grayscale just launched the Litecoin trust and institutional demand is surging as evident by the massive premiums Litecoin trust commands.
Litecoin is highly liquid and is still down 84% from its ATH. The breakout may be imminent so it is a good time to start accumulating within the S/R zone.
