Let me clear this confusion, current altcoins can never match up or can be considered as even competitors for Bitcoin as Bitcoin is level apart and once people vouched on ETH to topple bitcoin which never happened and will never happen considering Bitcoin network, market share and reliability (obviously) security as well. Bitcoin's price decides the market trend so there cannot any other coins which can compete with Bitcoin unless they overtake bitcoin in all the above mentioned aspects.
Let's stop comparing Bitcoin with other coins, may be it would be logical to compare or check which is the best altcoins or top altcoins.
the altcoins even just being put into one category "altcoin" because their market share is pretty irrelevant compared to bitcoin if not being clumped together.
basically the scenario where bitcoin getting overtaken by some random altcoin is very unlikely.
just see bitcoin ETF, selling like a hot cake where altcoin ETF are just massive failure with streaks of daily outflow. other altcoins haven't yet become a threat toward bitcoin.
