4 gestoras brigando pra te vender o mesmo título público com embalagem diferente.
Grão: 0,10%. Nu Asset: 0,19%. Galapagos: 0,20%. Itaú: 0,25%.
São 9 ETFs de duration constante na B3. A guerra de taxas da renda fixa chegou. E quem ganha é você.
Self custody is NOT dead.
SHUT UP!
If you believe you’ve been lead astray by being recommended using a cold wallet, you are mistaken.
When entropy is done correctly, cold wallets remain virtually impossible to hack.
Coldcard generated keys that could be cracked in minutes.
Wallets that generate keys using 156 bit to 256 bits of entropy will technically take thousands of years to crack.
And if you believe moving your crypto to an exchange is the solution, it’s not.
How do you think exchanges manage funds? Hmmm. Perhaps using a wallet?
One of the biggest exchanges in the world, Bybit, literally use Ledger wallets as part of their security protocol for users funds.
So, you can either keep your crypto in your own wallet where you maintain control and ownership.
Or you can send it to a company’s wallet where you lose control and ownership, and don’t gain anything in return.
To be clear. I am still pro self custody.
I do NOT recommend storing crypto with centralized platforms.
If you are a Coldcard user and temporarily need to move funds to an exchange, sure. That makes sense.
But the amount of influencers recommending moving your crypto to an exchange, which again, still utilizes wallets, is outright irresponsible.
Yes, what happened to Coldcard was horrible, but it doesn’t define self custody.
And don’t forget more than 1.5 Million of users Bitcoin was lost/frozen across just 7 different exchanges.
Over 1,300+ from Coldcard…
The data speaks for itself.
I’m going live today to talk about all this. I’ll pin the link to the livestream in the comments if you want to join or watch later.

🚨URGENT COLDCARD SECURITY UPDATE
Read carefully before acting.
👉Mk3 seed generated on 4.0.1+ without ≥50 private, independent dice rolls: begin a careful migration now.
👉Mk4/Mk5 <5.6.0 or Q <1.5.0Q: update first, generate a new seed, then migrate.

When I say “Never Sell Your Bitcoin,” I speak as one saver to another. I have never sold mine. Not one satoshi. Strategy is a public company, not my wallet. Since 2020, it has disclosed it may buy or sell $BTC to manage capital. Our shared conviction in Bitcoin remains unchanged.
🚨 LIKELY 4TH ORGANIZED WAVE COLDCARD ATTACK OCCURRING RIGHT NOW
THERE ARE STILL SIMILAR TXS IN THE MEMPOOL WAITING TO BE CONFIRMED AND THE PREVIOUSLY-CONFIRMED TXS SIGNAL RBF OPT-IN, CHECK YOUR FUNDS AND YOU MAY BE ABLE TO RBF YOUR WAY OUT OF THIS
pattern identified:
blocks 960,778 - 960,792 (last ~2.5 hours, still going):
• 218 transactions, 462 victim addresses, 216 fresh destinations.
• 388.92748828 BTC
• EVERY one has ZERO inputs predating the Coldcard firmware boundary
• Rate 13.8 sweeps/block vs 0.3/block in a pre-incident control window = ~45x elevated
• Topology is 1:1 — one fresh destination per victim, only ONE destination received two sweeps. No collector funnel.
• Some funds have already been swept into 2nd hop addresses.
these are LIKELY Coldcard victims -- they match the shape of coldcard vulnerable utxos and the elevated transaction pattern gives me high confidence they are another wave of attacks
MOVE YOUR FUNDS OFF COLDCARD DEVICES ASAP AND USE HIGH TX FEES
more details to come as this takes shape
More than a year ago, the House passed the Clarity Act.
There’s been progress since — thousands of hours of bipartisan negotiations took place at the staff and Member levels. The Senate Committees on Banking and Agriculture advanced their respective titles. And Senate Republicans produced a floor-ready product that, as I type this, is waiting for a vote.
It’s disappointing — but not surprising — that Senate Democrats are choosing politics on the cusp of a major victory for American leadership. Find another instance in history where Congress, when given the choice, opted to push an industry out of the United States rather than smartly regulate it. American Exceptionalism was once a bipartisan goal; if Clarity fails, I have serious doubts.
These same Democrats — many of whom have taken millions of dollars from the crypto industry — proclaim that Clarity lacks safeguards for consumers and falls short in countering illicit finance. Nothing could be further from the truth. Titles II and III materially uplift regulatory and compliance obligations for digital asset intermediaries, placing them on similar footing with traditional financial institutions. The Blockchain Regulatory Certainty Act — which Washington lobbyists have spun up as a boogeyman for certain groups of prosecutors and law enforcement — does nothing other than codify longstanding Treasury Department policy that’s remained consistent across Administrations: non-custodial builders and developers are not, and have never been, subject to registration obligations under the Bank Secrecy Act. And at this point, major law enforcement trades that once opposed the bill, including the Fraternal Order of Police, have now endorsed it.
The Senate needs to vote NOW on this landmark legislation. The truth is that Senate Democrats are afraid to advance the Clarity Act as they fear Senator Warren and the “Anti-Crypto Army” she once promised to build. In the days ahead, Leader Thune will put this theory to the test. Will Senate Democrats be on the side of American Exceptionalism, or will they opt to cede American leadership of a global industry for fear of the bespectacled squirrel’s Left flank?
America will lead or America won’t. It’s not more complicated than that. I believe Satoshi once said it best:
“If you don’t believe me or don’t get it, I don’t have time to try to convince you, sorry.”
Some AI humor @alighodsi speedran the entire AGI debate in 30 seconds in MS&E 435:
Q: who thinks we have AGI? → ~10% raise hands go up
Q: who thinks most people you interact with aren't as smart as the smartest model you use? → 90%+ hands go up
Q: ok, let's start over. who thinks we DON'T have AGI? 🤣
QED 🤡
Galípolo: "Ideia de que juros altos sempre beneficiam o mercado não se comprova"
Ele tá certo. E aqui os números que provam:
O que GANHA com Selic a 14,25%:
• CDI e pós-fixado: +14,25%/ano garantido
• LCI/LCA: isentos + carrego alto
O que PERDE:
• NTN-B 2035: taxa foi de IPCA+6% pra IPCA+8,2%. Duration 7 anos = quem comprou a 6% perdeu ~15% no PU
• Ações: taxa de desconto sobe → valor presente dos lucros futuros cai. Ibov negocia a 8x lucro
• Crédito: 2026 vai bater recorde de RJs pelo 3º ano seguido
• IPOs: zero. Bancos de investimento sem receita
O "mercado financeiro" não é uma coisa só. Quem acha que o mercado quer juros altos confunde o Tesouro Selic com a Faria Lima inteira
Quem ganha: quem tem dinheiro parado em CDI. Rentista, não mercado
For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.
AI will transform every industry, power every company, and be built by every country.
Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.
The world needs both frontier closed models and frontier open models.

O mercado acabou de fazer algo que não acontecia há meses:
começou a punir toda a cadeia global da IA, não apenas uma empresa.
"A queda do Google derrubou ações no Japão. A IA acaba de provar que virou um mercado global
👇🧵
- Você: "Minha casa valorizou 100% em 10 anos."
- Governo: "Parabéns! Quando vender, 15% do lucro é meu."
- Você: "Mas a inflação foi 70%. Meu ganho real nem chega a 30%."
- Governo: "Não importa. Eu tributo sobre os 100%."
- Você: "Você tributa a inflação que você mesmo criou?"
- Governo: "Sim, todo ganho de capital é taxado."
- Você: "Então você ganha 2 vezes com a desvalorização do dinheiro?"
- Governo: "É assim que o sistema funciona."
IPCA+ 8% ou Prefixado 14%? O cálculo que decide:
Inflação implícita = (1 + Pré) ÷ (1 + IPCA+) - 1
= (1,1486) ÷ (1,0836) - 1
= ~6% ao ano até 2032
Se inflação > 6% → IPCA+ ganha
Se inflação < 6% → Prefixado ganha
R$ 100 mil até 2032:
• IPCA+ 2032: R$ 202.733 líquido
• Prefixado 2032: R$ 196.666 líquido
Parece que IPCA+ ganha, mas só porque a simulação usa inflação de 5,11%. Se cair pra 4%, Pré vence
A resposta honesta: depende da sua aposta sobre inflação. Mas com fiscal solto e petróleo a US$ 91, apostar em inflação baixa é corajoso
Um professor da Arizona State analisou 29.754 ações americanas ao longo de 100 anos (1926-2025)
O resultado é brutal:
60% das ações DESTRUÍRAM patrimônio do acionista
O retorno mediano de uma ação na vida inteira: -6,9%. Negativo
Apenas 4% das empresas (1.082 de 29.754) criaram TODA a riqueza líquida do mercado. As outras 96% somadas deram zero ou menos
E a concentração tá piorando:
Em 2016, 89 empresas respondiam por metade da riqueza criada. Em 2025: 46 empresas
Apple sozinha: US$ 5 trilhões
Top 5 (Apple, Nvidia, Microsoft, Alphabet, Amazon): 21% de TUDO que o mercado americano gerou em 100 anos
O que isso significa pra você:
Escolher ação individual é apostar que você vai achar as 4% certas. 96% das vezes, você estaria melhor no CDI
O argumento mais forte que existe a favor de ETF passivo. Não é opinião — são 100 anos de dados
E o detalhe que ninguém fala: o segredo das 4% vencedoras não foi retorno de 100% num ano. Foi retorno de 12-15% ao ano durante décadas. Composição

O maior fluxo da história do Bitcoin depende de 3 destravamentos em sequência, e 2 já estão em andamento:
1. CLARITY Act: aprovado na Câmara e no comitê do Senado, falta só o plenário. Classifica Bitcoin como commodity digital e dá a segurança jurídica que banco americano exige;
2. Basileia: risk weight de 1.250% obriga o banco a reservar $1 de capital pra cada $1 dólar de $BTC, isso é basicamente uma proibição na prática. O Comitê já iniciou a revisão do padrão, atualização prevista ainda este ano;
3. Fluxo: bancos globais carregam $190 trilhões em ativos, o Bitcoin inteiro vale $1,27 trilhão, e fluxo não move preço 1 pra 1.
A matriz abaixo é o MBFM, meu modelo de multiplicador de fluxo bancário que uso nos meus relatórios, marco um piso conservador da literatura.
O maior comprador da história ainda não recebeu permissão pra comprar.
