If they dont want bitcoin in the first place they should have speak about it since before but why now that bitcoin price is highly increasing and paint bitcoin negatively. But it wont work and this strategy wouldnt buy consensus to the society because we are already aware of what is the truth. That cash/fiat money has been used many times in those crimes more than bitcoin.
Back in the early days banks were likely assuming that people would abandon Bitcoin and everything related to crypto, but now the adoption is increasing significantly, and that in a very short period of time, they finally start to take it serious. And yes, blackmailing Bitcoin won't work anymore -- they are too late for that. Ultimately, we shouldn't be surprised to see them act like this, because they very well understand that Bitcoin has the potential to disrupt their entire way of operating. Let them talk as much as they want, their words hold no actual value since we know it comes from their desperation.
