In my opinion, no altcoin even ethereum will replace Bitcoin. Looking at the current growth of Ethereum, you may think that it may replace bitcoin. But the reality is different. Rather, I wonder when BNB replaces ETH.
Yes, replacing Bitcoin is not an easy thing to do, as well as BNB who wants to replace ETH, because the two coins are already very strong in the crypto space so it is very difficult to fight, especially ETH and BNB are coins that very often follow the movement Bitcoin price, it is clear they will find it difficult to fight Bitcoin.
