I think there is no other coin that is able to take the position of the king over bitcoin-ethereum, because the coin has a very high value and a very sophisticated blockchain system, so it is very difficult to beat because btc is the mother of all coins.
Indeed, BTC is made as if by a perfect coin, we hope that this will be so, because in general, there are a lot of options tied up there that depend only on the community, the only problem is the power of 51% percent.
Bitcoin will always remain the king.No other cryptocurrency or altcoin has that much of potential and capability to overtake bitcoin.Bitcoin has the largest number of users among all the cryptocurrencies and altcoins.Bitcoin has made many people rich and even billionaires invest in bitcoin.Bitcoin is a money making machine and we should try this definitely.Bitcoin is always the hot topic in the market regardless of what is the value of bitcoin.
