There is no altcoins or tokens can replace / take over bitcoin, and Binance is unable to do this for sure. Binance, in most positive scenario, can only take over Ethereum second position on coinmarketcap.com and in crypto space. However, I doubt that Binance coin can take over Ethereum, at least in next two years. Honestly, I don't believe BNB can do this in so many coming years, not only two years.
I agree, it is difficult to replace Bitcoin both in terms of market cap value and investor confidence. BNB Coin is a good long term investment but I am not sure that it will replace Bitcoin because the use of BNB Coin is still limited.
