yeah they also sniped those memes very early like basically first second the pool is created they bought it and they usually doing the same thing to other 100s of memes and putting money at risk.
which kinda make sense if at some point they make it big and that one profit could outweigh all the money they lose, still there's no guarantee that 1 out of 100 meme released there will be one that gonna give us profit.
it could be 1 out of 1000 or 1 out of 10000 meme that's profitable, we don't know for sure.

that's why even sniping early also depends heavily on luck.
