If altcoins aren't dependants on Bitcoin price or value one altcoin would have over throne Bitcoin, if it was a different story that altcoins don't rely on Bitcoin bullrun I believe Bitcoin won't be the 1st today, am I wrong or right?
Still depends on trading volume and market cap, even If Bitcoin is the first and failed to maintain a high marketcap over others them it will lose its position on coinmarketcap, Bitcoin isn't the first because it's the first crypto coin but because it has the highest marketcap, well supported too
