    Just revealed: FinCEN explicitly told prosecutors Samourai Wallet wasn't a money transmitter due to its non-custodial design; DOJ prosecuted developers anyway, suppressing exculpatory evidence for a year.

    Right now there is $40 Billion in the ESF that can be used to buy Bitcoin in a “budget neutral” manner under this Executive Order. Let that sink in…

    The SBR EO is more bullish than most onlookers were anticipating: “The Secretaries of Treasury and Commerce are authorized to develop budget-neutral strategies for acquiring additional bitcoin, provided that those strategies have no incremental costs on American taxpayers.”

    The seizure of $15 billion in bitcoin from a criminal enterprise built on human trafficking and financial fraud is exactly the kind of outcome the Strategic Bitcoin Reserve was designed to enable. Under Section 3(d) of the SBR Executive Order, any coins that can be traced to

    Today I’m sharing an open letter to Democratic Senate offices urging them to reject Democrats' proposed DeFi framework and preserve the developer protections at the heart of the CLARITY Act. Code is speech. Publishing software is not a crime.

    For SBR skeptics: would you rather these coins hit the market all at once in a Government auction, or are you glad that Treasury is now obligated by executive order to hold the ~127k BTC on our national balance sheet?

    Replying to @zackbshapiro
    Unlike the text of @DavidSacks’s tweet, the actual text of the EO *directs* commerce and treasury to develop strategies to buy BTC, rather than merely empowering them to do so.

    This is the former Chief of Staff at the @SECGov in the Gensler/Warren era. Does not understand (or care) about the difference between a custodial exchange and a peer-to-peer protocol—which is of the utmost legal importance both to Securities laws and Illicit Finance

    For Bitcoiners who upset about the Samourai Wallet outcome, this is our best shot going forward. @RealAngelaMc was one of the main driving forces behind the Ross pardon, so please reach out with any support you can give 👇🏼

    The Samurai Wallet sentencing is terrible. I am working on it. I am working on a LOT of these cases. I need Bitcoiners to flex their influence right now. You need to make calls to the admin. We will not win this in woke courts. We can win in the Whitehouse.
