as we know that Binance has two projects, that is exchange and smart contract, then the total supply of BNB is around 160m and will burn every quarter, so the total supply of BNB will be less every quarter and with the current price of BNB ($410), then I think the price of BNB is still very low, because with a small total supply of BNB and BNB is one of the most popular projects (top 5 on coinmarketcap), then I think the price of BNB can still increase very high and reach at least $1500 (I think it's a decent price for BNB), therefore now is still the right time to invest in BNB and hold it for the long term, because at this time you can still buy BNB at a low price.
1500$ price for BNB for me is achievable with the next 5 years. The fact that BSC is becoming the alternative for ETH costly fees, this coin is becoming more and more traction throughout the years. However, we have to also think that the rise of its price will also mean the increase in fees. It would not be as costly as ETH, but it will be a dollar per tx soon.
