2021 BNB Ecosystem: BNB has been rising continuously, BSC chain gas fees are low, and a large number of meme tokens are issued on BSC every moment, with a small number of high-quality tokens appearing.

2021 ETH Ecosystem: ETH has also been rising continuously, with both meme tokens and high-quality tokens. The most important thing is that there are many innovations, but various innovations are slow and take a long time to be recognized for their value.

At that time, everyone focused their attention on BSC's meme tokens and high-quality tokens, as most people preferred to get rich quickly and disliked accepting new things.

NFTs, GameFi, etc., on ETH were temporarily set aside after being speculated on, only to experience a massive explosion in the later stages of the bull market.
