Even if Bitcoin's market dominance drops to 25% bitcoin will still be the dominant force. Remember, the cryptocurrecy markets is easily swayed by news(both fake and legitimate), especially to most altcoins. Bitcoin will still be the most decentralized, most secure, and most globally adopted coin compared to all the other coins/tokens combined.
This is what i think so...i don't think that there is a token or coin will have a better dominance percentage than bitcoin
