#Bitcoin Fees: Multisig vs. Singlesig 📊
Multisig wallets offer enhanced security, but they come with higher transaction fees.
Here's a quick comparison:
* 2-of-3 multisig: ~50% more expensive than singlesig.
* 3-of-5 multisig: ~100% more expensive.
* 4-of-7 multisig: ~150% more expensive.
Why? Multisig transactions are more complex, requiring more data.
Is it worth it? 🤔 If security is paramount, YES! 👍

Spectacular footage of space debris burning up in the atmosphere over Argentina. Each year, an estimated 100-200 tons of space junk re-enter Earth's atmosphere.

🚀 Today we’re supporting @Andreas Griffin
from Bitcoin-Safe.Org with 1,000,000 satoshis for his work on Bitcoin Safe – a beginner-friendly multisig wallet for Mac, Windows, Linux, or anywhere Python runs. Why this matters 🧵👇
🔧 Development of Specter Desktop is no longer a priority at Swan. A vital open-source wallet has essentially become abandonware – leaving a painful gap in the Bitcoin ecosystem.
💡 Andreas, a former Specter developer himself, recognized this gap – and with Bitcoin Safe created a brand-new solution that already goes beyond what Specter offered.
🔒 What makes Bitcoin Safe special:
An open-source wallet focused on multisig and hardware wallet integration. It combines the strengths of Electrum, Specter, and @mempool – with Nostr functionality added in.
🧙 The beginner-friendly multisig wizard makes secure Bitcoin self-custody accessible – even for non-technical users.

⚡️🇫🇷 🎥 NEW - To instill fear through a strategy of shock and awe, the French army organized an urban warfare exercise in the city center "to prepare for the evaluation of a conflict of this kind in the years to come".
Several scenes show soldiers firing blank shots amidst bystanders and children in the free zone (here in Fréjus).
Preparatory to the Russian invasion narrative, do you think? #asknostr
