Of course the bankers don't like bitcoin. Not only bitcoin, they hate all those "decentralized" crypto currencies. But they do love cryptocurrencies that are centralized. They have their own reason for hating it though. If decentralized currencies become mainstream, the bankers are going to be in danger since people would no longer be in need of a centralized financial institution. Not sure why you think "wall street" hates bitcoin too.
Thats why they buy the most of Bitcoin once they get a lot I think they just crash it.
Or is it because they love bitcoin and sees a very good opportunity in making profit from it?
maybe they like bitcoin but bankers job is not make profit their mission are to give out loans and make sure that we dont make profit.
if we would become wealthy the value of money goes down so they are like financial gate keepers to make sure we stay down
