From all angles and all indications you don't need to be told that bitcoin rules the crypto market and its dominance its respected by almost every altcoin on the market
in my opinion Bitcoin is the king of all coins and no one will replace a strong king what ever happened on the market no matter who owns the market for now but as they say once the king is always a king. So no one can replace a king like Bitcoin.
There are so many alt coins on the market now today that is a threat to the survival of Bitcoin on the market
Bitcoin is the clear winner.All the other cryptocurrencies and altcoins are regulated with respect to Bitcoin only.Bitcoin is the father of all the cryptocurrencies and it is the most expensive and valuable cryptocurrency in the market.No other altcoin has the potential and capability to overtake Bitcoin even in the coming future.Bitcoin has the largest number of users in the market and its demand is also higher than the other cryptocurrencies and altcoins.Bitcoin can be called as the global currency.
