I think BNB can still go up higher than the current price, even though BNB has already crossed 640 $ but I am sure BNB will reach 1000 $ soon, because the potential of BSC is still very large, even after ETH lowered their gas fee, the BSC gas fee is still keep it cheaper
With regards to the gas fees, no question about that, Binance Smartchain still have a better transaction fee compared to Ethereum network and of cause this is why most projects switched to BSC in recent times and this is bring a lot of activities there and more project development is still going on too and the ether gas fee that is said to be low, a $4+ gas fee is still not executed for more than a day now that is not cheap.
That's the very advantage of this chain and by that developers are switching over, with low transaction fees more investors and traders
will likely gather interest usig BSC than ERC.
Slowly but it's getting there, just like how ETH has been announce before, the countdown are continuous and day by day the value are
trying to breakout.
Success with the development really affects the current value, $1K is not far to reach, just keep your patience and hold still.
