Lol ^^ I love this narrative, it'd be beautiful if it was real but sadly I doubt it is.
JPM is an investment bank whom buys on behalf of their clients. I highly doubt JPM was buying for their corporate accounts, they are smarter than to open themselves up to litigation with blatant manipulation like that.
Yes, Bitcoin is a semi-unregulated "asset", but the ETN purchased by JPM Europe division is NOT, it is a publicly traded note that follows the same rules & regulations as any other ETF, ETN, or stock. To directly manipulate bitcoin is to indirectly manipulate the bitcoin ETN's and that my friend IS a punishable offense.
Jamie Dimon is laughing at us right now, probably saying "Bitcoiner's just doubled down on their own stupidity". Just saying
JPM might have an opinion about something, but that doesn't mean that they stop their clientele from purchasing that something. After all, you are free to be stupid with your own funds, he just isn't going to hire you.
