nope, Bitcoin is a central of any cryptocurrency nothing any altcoin can placed 1st position in cryptocurrency than other, even any speculate from pro trader, specualtor, investor or another shit people
Yes no one can overtake bitcoin as the top crypto existing, because it is the king and started it all.
On the other hand eth is also on top of the altcoins and one of the reliable coin just like bitcoin. Hence I think we must be contented on the spot eth had, in the future it will rise too together with bitcoin and other established altcoins.
Since the beginning of the famous bitcoin, so many people have tried to make crypto better than bitcoin. honestly many coins are considered to be able to exceed bitcoin, it's just that until now it hasn't been proven, in fact, they all follow the movements of bitcoin. even some coins have exceeded the price of bitcoin but not many use them and fall.
