4th solo Bitcoin block in one week! 🔥🧡 Solo miner with S19 has just found a Bitcoin block 944,306 worth 3.128 BTC #bitcoin #mining

Bitcoin's mined supply just hit 19,999,859 coins. That's already 95.24% of the full 21 million cap, and we're super close to crossing that big round 20 million mark. Crazy to think it's been 17 years since the genesis block back in 2009. #bitcoin #nostr

Look at the top 10 richest Bitcoin addresses! Binance cold wallet – ~248,600 BTC Another Binance cold wallet – ~157,400 BTC Robinhood cold wallet – ~140,600 BTC Bitfinex cold wallet – ~130,000 BTC ...and so on. Just these few exchange-controlled addresses alone hold hundreds of thousands of BTC (Binance's visible ones top 400k+, Robinhood and Bitfinex add another 270k+). That's a massive chunk of supply still sitting on centralized platforms, not in people's own custody. Exchanges as a whole? They custody way more Binance alone has reserves in the hundreds of thousands of BTC for users, Coinbase even higher in some reports. All that BTC is "yours" only as long as the exchange stays online, doesn't get hacked, doesn't freeze withdrawals, or doesn't go the FTX route. History shows it's risky.Remember the golden rule: Not your keys, not your coins.If you're still leaving your stack on an exchange in 2026 because self-custody feels complicated, setting up a hardware wallet, multisig, seed backups, inheritance planning, avoiding common mistakes, don't sweat it. DM me here on Nostr (or reach out on X "@TreasuryOS" if you are cross posting). We'll walk you through it step by step, hand-hold the whole way: recommend solid wallets, explain air-gapped signing, test small amounts first, set up watchtowers if needed, whatever fits your stack size and comfort level.No judgment, no rush, just real help to take full control of your Bitcoin. Sovereignty feels good once you get there. Who's ready to move their coins off exchanges this year? Drop a message, if you are thinking about it. #Bitcoin #SelfCustody #NYKNYC #Nostr @Student of Bitcoin @bitshala

It is very expensive to be poor. Because when you are poor, everything costs more: • You can’t buy in bulk, so you pay higher unit prices • You can’t afford quality, so cheap things break faster and need replacing • You can’t access good credit, so you pay higher interest • You can’t invest early, so you lose years of compounding • You can’t take risks, so you stay stuck in low-paying paths and fear • You can’t afford nutrition, so your health deteriorates • You can’t afford events or conferences, so you don’t get exposed to high-value network or opportunities • One emergency can wipe out everything Poverty isn’t just a lack of money. It is a tax on the poor that keeps them poor. #bitcoin #finance #nostr

China’s Bitcoin mining is back strong with cheap, surplus power & underground rigs. It’s now the 3rd largest miner at 14%+ global hashrate! ⚡️ What’s your take on this mining comeback? 🤔👇 ++Bitcoin mining is booming again in China mainly because of abundant and very cheap electricity in regions like Xinjiang and Sichuan, where excess energy cannot be transmitted out and is utilized locally for mining. #Bitcoin #Mining
