I think bitcoin will remain the King of crypto and do not see any other coins getting anywhere close to its value in the next year. Ethereum will probably remain second most valuable at approximately 10-15% of bitcoin value. This has typically been the way it works. When bitcoin jumps or drops, altcoins follow suit.
BTC will remain the king for some years to come atleast and not or say hardly any coin can have such a huge momentum in so short while. Unless we hear something specifically for a coin from some country supporting it or like that than only it can be little danger to the btc value as that coin will start to rise rapidly.
