It's obvious that they are simply trying to do what is best for their corporation, which is often to give off the impression of something that you're not, or take a false stance.

It doesn't matter what other corporations think about bitcoin, no matter how large they are. This is the fundamental thing that most people are getting wrong, in my opinion, which is caring too much about what executives of certain companies have to say. The BTC network is decentralised for a reason, and that reason is exactly that of no one is able to ban, restrict, or manipulate the bitcoin network regardless of whether they're a centralised institution on a mass scale or not.

JPMorgan is probably only interested in BTC as a means of making profits, not so much so as an actual viable means of payment or currency. Thus, it is easy for them to shift stances like this, and it makes sense given that they are also somewhat invested in having a crypto venture at this stage. I would personally pay no close attention to any of this, because Dimon or other execs could come out tomorrow and say something completely different, should they change their own outlook regarding their crypto project.
