but BNB will not be able to get past Bitcoin and ethereum because both cryptocurrencies already have large and loyal followers. BNB will still be in its position and is the most suitable actually I think if BNB continues to be in position 3 like a few weeks ago.
Why not just be grateful that BNB is now in the top 4 position? That's a very good achievement already, from when (2019) the time the OP posted this thread. Indeed, BNB has come a long way already but I don't think this will surpass btc and eth as well. Binance platform is a centralized one, so don't think that a centralized in nature will come to be at the top, let alone beats bitcoin.
