Everything will depend on whether the BSC network holds its place or not. If the Commissions in the Ethereum network fall to a minimum, which is quite likely, then there are risks that the BSC will no longer be so attractive.
However, I am sure that CZ Binance has its own plan in this regard, so I absolutely bet on BNB.
But at the current price, I guess its already overvalued because of the bull run and we should be careful with that especially if we are just aiming for short term investment. For long term, obviously its undervalued as BNB could compete with ETH in the long run but I would not ride at the FOMO, wait for the right timing to accumulate if you are a new investor. Problem is, with the FOMO, everyone is riding at a bad timing.
