Well, according to the stats on the site mentioned above, this meme hype around BSC was indeed short-lived. At least today, the daily trading volumes in the BSC network have already dropped to ~$900 mln, and as a result, BSC is now in second place by this metric.
However, if CZ promotes some meme tokens again, it may create another hype and, consequently, boost trading volumes.
I don't know if it's only me, but based on my experience, projects or in this case, meme coins that have been promoted by a single influencer is indeed short-lived.
McAfee promoted ICO's in the past. Short-lived
Roger Ver promoted some ICO's in the past as well. Short-lived.
Some influencers online promoted numerous projects as well. Short-lived.
...and it will be the same with CZ.
For me, investors already learned their lesson with pump.fun. For me, investors don't want to risk their money with some new meme coins anymore. Yes, there will be some investors that loves gambling and will still do it, but most will not. As for CZ promoting meme coins, I hope that he will not continue this kind of thing as it only just creates fake volume on the BSC.
