It's very easy calculation for BNB. There are over 165 millions BNB in circulation. With current price which is around $450 the market cap is $74 billion. Hence, if you're asking if BNB going to reach $5000 price then it's not going to happen anytime soon. There is simply no space at the moment to put such market cap. If BNB going to reach $5000 then its market cap exceed $825 billion which is about current market cap of Bitcoin. The answer is that simple. I think that $1000 in next 2 years is more realistic for BNB.
Yes we are looking at it realistically as it is today.
What you say is true it is not easy to reach the price of $ 5000 in a short time.
To reach just $1000 it takes some know what else to get past the capacity of the bitcoin market space is really a shocking thing.
