Considering there are thousands of coins and tokens out there, what sort of dominance should Bitcoin have which shows that even though it remains the dominant force there is still a lot of space for others to narrow the gap?
IMHO, nothing! Bitcoin already have everything the highest price, investors and adoption. There's no need for btc to feel threatened anymore because he is currently unbeatable. Altcoins should do a lot of work first if they really want to kick btc on his throne but how? I don't know either (even Ethereum, the closest to him, was still no match), hmm maybe if the world suddenly got brainwashed, sell all btcs and buy a particular alt lol
