No, BNB cannot be called a future bitcoin. This currency has become popular lately due to the fact that thanks to it, IEO is held on the Binance platform. I would not consider BNB as a serious investment.
Why not ? If that what others think and say then let them . there is nothing wrong with that . its not really a big deal . we to know our selves that bitcoin will always be the king of all cryptos because bitcoin is the first and the original plus bitcoin is also the most popular and most recognize crypto around the world , its value says it all .
There were lots of competitors for bitcoin on the past including eth and bch but all of them lost the battle , eth and bch are i think more superior when compare to bnb .
