bitcoin and litecoin is a parable that much in comparison. thus to call litecoin as the next bitcoin certainly also is funny. probably still a lot of altcoins which is much better than litecoin and it deserves when referred to as bitcoin is next.
Like earth with the sky, if there are still those who argue that the next bitcoin is litecoin. Litecoin is indeed a strong coin and has a lot of community but its prestige is still unable to keep up with bitcoin. Until now bitcoin is still a bitcoin that has more value than other coins.
The market still respects this as the king of coins. Litecoin still takes a long time to attract the attention of bitcoin holders.
