The leading MEME coin on the BSC chain, why is everyone playing copy and paste to pump it?

Now, every once in a while, there’s an old MEME coin on the BSC that surges, from Hakimi to the vulgar penguin, and then to last night's GIGGLE. Each time a coin leads the rise, many old coins will follow along, getting a piece of the pie.

Following the upward trend to absorb some liquidity is not a big deal, but some coins don’t just follow the trend; they are closely mirroring the movements, and they are not small caps.

Take yesterday's GIGGLE for example, it started to pump at 5 PM and dropped by 1 AM, forming an arch shape. The hourly chart of $4 and Binance's life is almost identical to GIGGLE, even the timing of the pump and drop and the pullback magnitude are quite similar.

Could it be that behind these coins, there is really the same operator at work?
