I do not believe in a rumor. and also about the next bitcoin is litecoin. why?
because I see LTC has a slow development, and also has no plan, so when bitcoin down, LTC prices can not survive, even down as well.
and when compared to the NEO, I prefer NEO or ZCash rather than LTC.
DOn't believe in rumors. Litecoin is good coin but it is only altcoin that is compatible to bitcoin. Bitcoin is the king of coins. There are no coins that can have the same spec as bitcoin that replace the hegemony of the price. ETH and NEO are great coins too but they can't replace bitcoin until now.
