The policy would mark a big shift for JPMorgan’s chief executive Jamie Dimon, who eight years ago branded bitcoin a “fraud” that would “eventually blow up” and was only useful for drug dealers and murderers. JPMorgan could start lending directly against crypto assets such as bitcoin and ethereum next year, according to people familiar with the matter, who cautioned that the plans were subject to change. JPMorgan declined to comment.  The move would underscore the extent to which big banks, and the regulated financial industry more broadly, are opening up to closer interaction with cryptocurrencies.

Fascina-me como figuras tão ideologicamente díspares como Estaline e Putin podem coexistir nos mesmos altares. Quando a ideologia cede à estética do poder e do nacionalismo, resta apenas a veneração da autoridade como fim em si.

Hallucinations are a very hard problem to fix because of the probabilistic nature of how these models work,” said Amr Awadallah, a former Google executive and founder of Vectara, a generative AI agent start-up. “You will never get them to not hallucinate.”

More than 14,000 "Islamic" coins (coins produced within officially Islamic polities) were buried by VIKINGS on a Swedish island in ~850-900. Numismatists can easily overwhelm me with detail, but boy when they know big things... they're big! #FollowTheMoney

Blockchains are pretty useless for payments, I agree. I think the real worry is that the big tech platforms will now launch stablecoins and process most of the payments off-chain...

From fintechdystopia.com
In addition to their political influence, Silicon Valley’s largest tech platforms already have millions if not billions of users and all kinds of personalized data that will help target advertising and services to those users. These platforms are therefore very well situated to push the use of their stablecoins for convenient payments on their platform. These platforms also have plenty of money they can use to cross-subsidize the financial services they offer, making it hard for others to compete – once entrenched, the revenues from their financial services will then be available to subsidize the platforms’ other products and services. Because it will be so easy for Silicon Valley’s largest platforms to capitalize on this platform power to encourage their users to adopt platform-affiliated stablecoins, I don’t think that Wall Street banks (who have comparatively little data about their customers, can’t offer non-financial services, and don’t always pay much interest on customers’ deposits) should be quite so complacent about their market share. The exponential growth of AliPay and WeChat should at least give the Bank of Americas of this world pause. While it’s not an apples-to-apples comparison given that payment and banking options in China were pretty limited before the super-apps came along, AliPay and WeChat became the dominant providers of financial services in China within the space of about seven years. They were able to do so even though their customers still needed a bank account to use these super-apps. U.S. Congress is about to go even further, setting up Silicon Valley to cut banks out of the process entirely.

embrace Matt Levine thought
I have written before about my own fantasy for consumer securities regulation, which would solve all of these problems but which would probably face some political hurdles in getting enacted. It goes roughly like this: 1. Anyone can invest all they want in a diversified portfolio of approved investments (non-penny-stock public companies, mutual funds and exchange-traded funds with modest fees, insured bank accounts, etc.). 2. Anyone can also invest in any other dumb investment; you just have to go to the local office of the SEC and get a Certificate of Dumb Investment. (Anyone who sells dumb non-approved investments without requiring this certificate from buyers goes to prison.) 3. To get that certificate, you sign a form. The form is one page with a lot of white space. It says in very large letters: “I want to buy a dumb investment. I understand that the person selling it will almost certainly steal all my money, and that I would almost certainly be better off just buying index funds, but I want to do this dumb thing anyway. I agree that I will never, under any circumstances, complain to anyone when this investment inevitably goes wrong. I understand that violating this agreement is a felony.” 4. Then you take the form to an SEC employee, who slaps you hard across the face and says “really???” And if you reply “yes really” then she gives you the certificate. 5. Then you bring the certificate to the seller and you can buy whatever dumb thing he is selling. 6. If an article ever appears in the Wall Street Journal in which you (or your lawyer) are quoted saying that you were just a simple dentist, didn’t understand what you were buying and were swindled by the seller’s flashy sales pitch, then *you* go to prison.

Mudar para T+1 é uma decisão necessária. Uma liquidação mais rápida reduz o risco e está alinhada com os mercados globais, mas esta frase da Albuquerque, embora pareça evidente, não faz sentido. A liquidação instantânea parece ótima, mas tem sérias desvantagens.

The Execution of the Doge, by Delacroix, 1825. He was beheaded for attempting a coup d'etat.
Apropos of, you know, absolutely nothing at all.
Delacroix's dramatic oil shows the aftermath of the beheading of Doge Marino Faliero on the famous staircase in the Ducal Palace in Venice.
