But those "fake txs" have to be honored in some form or fashion, by proxy these tx could drive the price downward but others not participating in this collusion would have another spot prove that deviates from the colluding CEXs. So how would everyone all over simultaneously make this possible that they all followed the same pricing? I mean isnt non kyc dex like bisqs/hodlhodl/vexl/peach  premium really the "true" free market rate anyhow? I'm still trying to understand how any overt collusion for massive price swings down would continue to be successful.
