One of the biggest highlights from @BTCPrague: Telling my story with @vexl and seeing people realize how easy P2P really is Bitcoin is for everyone. Let’s keep building. #P2P #BitcoinEducation

Crossing borders with Bitcoin? Your hardware wallet is a liability. Customs can seize devices. Border agents can compel passwords. Airports are high-stress environments where mistakes happen. The best travel security: keys that aren't with you. #Bitcoin #SelfCustody #Security

Great bitdev session at @pow_space with @tierotiero @giacomozucco @PalazzoVincenzo and many many other Bitcoin devs.

Understanding UTXOs changes how you think about Bitcoin ownership. There are no accounts. No balances. Only spendable outputs controlled by keys. Read full article: 👉️ blog.bitvault.sv/bitcoin-doesnt…

A 48-hour withdrawal delay is not an obstacle. It is a security layer. If an attacker gains access to your wallet, the delay gives you time to detect and respond before funds move. Friction is protection. #Bitcoin #SelfCustody #Security

@vexl @CedolinRoberto Well done Roberto. I'm so happy you joined the effort to help the whole Italian community growing! 🚀

Ever wondered why Vexl is booming in Italy? 🚀🇮🇹 Because of people like @CedolinRoberto Vexl’s Italian Community Manager and others 🫂 He’s putting real work into making P2P stronger and local BTC communities more accessible. Happy to have him onboard. Say hello, guys! 🙋🏻‍♂️

What an honor 🖤 Our co-founder @LeaPetras discussing P2P Bitcoin, noKYC and much more stuff worth of listening to! Live on Citadel Dispatch pod @ten31funds 🎙️

A Bitcoin wallet is basically a UTXO calculator. The number you see is just a UI abstraction. Underneath, the network tracks independent outputs locked by scripts. Learn more here: 👇️ blog.bitvault.sv/bitcoin-doesnt…

Studying or reviewing with @AmityAge is always a blast!

How many physical attacks like this could have been made impossible by @BitvaultApp ... hurry up ! check bitvault.sv out

Bitcoin transactions are irreversible. Once confirmed, there's no "undo" button. This finality is a feature—but also an attack vector. A thief needs only minutes to drain funds forever. BitVault's 48-hour delay creates a critical window to detect and stop unauthorized withdrawals. #Bitcoin #SelfCustody #Security

🚨 Last Prague episode of Cypherpunks in Cars is live. Cypherpunks knew it from the very beginning that privacy would matter in the digital age. 33 years later, it matters more than ever. Reclaim back your privacy now!

Cypherpunks write code! The Cypherpunk Manifesto was published on March 9, 1993 by Eric Hughes. Happy Cypherpunk Day 🖤

Most Bitcoin users think they have a balance. They don’t. Bitcoin doesn’t track balances at all. The protocol only tracks UTXOs — Unspent Transaction Outputs. Your wallet simply sums them and displays a number. Once you see this, Bitcoin stops looking like a bank account and starts looking like a distributed ledger of spendable outputs.

If you are using KYC exchanges... STOP it, get some help!

Education is the base layer for business growth.

@LuganoPlanB 4th birthday celebrations just kicked off in Lugano.

If your journey into Bitcoin starts with uploading your passport, we are afraid you took a wrong turn.

Most Bitcoin losses don’t come from weak cryptography. They come from poor authority design. A mnemonic is pure power. The architecture around it decides whether that power can be abused. Detailed explanation. 👉 blog.bitvault.sv/from-mnemonic-…

Your seed phrase can be 256-bit AES-encrypted and still be worthless if someone physically threatens you. Cryptographic security stops computational attacks. Human-factor security stops coercion. These are different problems requiring different solutions. @bitvaultapp

Mnemonics don’t store Bitcoin. They store the ability to generate private keys. That distinction changes how you think about security. If keys = authority, design matters. Deep dive: blog.bitvault.sv/from-mnemonic-…
