💪 Bought the top, keeping the tradition alive. 🕕 Saylor took a two-month break while BTC was chopping around $60K. Then came back right as BTC ripped to $80K — and bought another 4,603 BTC at an average price of $80,318. Absolute legend 🫡

crypto projects just discovered the Wall Street playbook. $640M has already been spent on token buybacks in 2026. that’s a new record. Hyperliquid and pump.fun account for nearly 90% of it. and Hyperliquid has reportedly been using 99% of its revenue to buy back HYPE. crypto used to be: “number go up because community.” now it’s: revenue → buybacks → reduced supply. we’re slowly reinventing the stock market on-chain. 💀 #Hyperliquid #Crypto

Google just made a $12.2B bet against Nvidia dependence. Google is expanding its custom AI chip push with Marvell — and the deal gives it the option to buy up to $12.2B of the chipmaker. the bigger number? the partnership could generate up to $120B for Marvell through 2033. Big Tech isn’t just buying AI chips anymore. they’re trying to control the entire stack. chips → data centers → models → users. the AI infrastructure war is getting ridiculous. 🤖

🤨 Will BTC hit $200K in just a year? 📈 The Seller Exhaustion Indicator is currently trending on X, having fallen to one of the lowest levels in BTC’s history—~0.007. There have been 11 such instances in total, and in all previous cases, Bitcoin closed an average of 155% higher one year later. 😑 Isn’t there a bit too much euphoria in the market right now? Isn’t a major correction on the horizon?

AI just found serious flaws in a Bitcoin hardware wallet. BitBox says frontier AI models helped its engineers uncover: → 2 severe firmware vulnerabilities → 1 bootloader issue no funds were stolen. but here's the interesting part: AI isn't just being used to attack crypto anymore. it's starting to find the bugs before hackers do. 🤖 hardware wallets are becoming an AI security battlefield.

BYBIT lost $1.46B. now it says it stopped another ~$700M from disappearing. after one of the biggest crypto hacks ever, Bybit says its security systems prevented around $700M in potential user losses in H1 2026. AI threat detection. real-time on-chain monitoring. transaction screening. apparently losing $1.46B changes your security priorities pretty fast. 💀

🚨 2 BILLION monthly downloads. 📦 1,300+ npm packages. 🦠 one self-spreading worm. ChainDrop infected legitimate software packages used by developers around the world. one npm install was enough to run the malware before installation even finished. then it started stealing: 🔑 GitHub and npm tokens ☁️ AWS credentials 🗄️ database passwords 💰 private keys 🤫 cloud secrets and used them to infect even more packages. the code looked legitimate. the update was signed. the malware came through the front door. 💀 #CyberSecurity #CryptoSecurity

😳 BINANCE HANDED A USER’S DATA TO RUSSIAN AUTHORITIES. A Russian IT specialist allegedly donated just over $700 to Ukrainian military-linked groups. Binance reportedly provided investigators with: → his full transaction history → passport and home address → phone number and date of birth → a copy of his Bulgarian residence permit That data became key evidence in a terrorism-financing case. Binance says it simply responds to lawful requests from authorities worldwide — and that no privacy rules were violated. The awkward part? Binance claimed it had fully exited Russia back in 2023. 😬 crypto may be decentralized. your KYC account definitely isn’t.

171 Cardano wallets were drained. the attackers didn’t steal seed phrases. they reconstructed private keys from public transactions. a flaw in SecondFi’s transaction signatures leaked information every time an affected address was used. the more you transacted, the more the blockchain revealed. your wallet history was enough to break your wallet. that’s terrifying. 💀

$88M gone because a hardware wallet couldn't generate random numbers properly. yes, really. researchers linked a flaw in COLDCARD's random number generation to a massive Bitcoin theft. ~1,196 addresses were hit in one wave. the attacker swept them in just 41 minutes. hardware wallet. offline keys. still not automatically safe. crypto security keeps finding new ways to humble everyone. 💀
