Try explaining your reason for owning Bitcoin without saying it will reach a particular price. Would you talk about saving, ownership, freedom, inflation, family, or something else? 💬 If Bitcoin’s price stayed disappointing for five years, would your original reason for owning it still hold up?

I own Bitcoin because I believe saving should actually mean saving. 💰 If I work today and choose not to consume what I earned, I should be able to preserve that value for tomorrow — without someone else having the ability to create more units of the money I saved and dilute my share. 📉 Bitcoin gives me something I can truly own. 🔑 ✅ I can hold it myself. ✅ I can take it anywhere in the world. 🌍 ✅ I can send it to anyone without needing permission. ✅ And no government, bank, company, or individual gets to decide to create another 21 million Bitcoin. But ownership is only half of it. The other half is the freedom to build. 🛠️ I can program my finances directly — with AI as my co-pilot 🤖 — and create complex financial structures without begging the banking system to allow me. No applications. No gatekeepers. No waiting for permission that may never come. If I can imagine a way to move, save, or structure my value, I can build it myself. ⚡ That matters more to me than what Bitcoin trades for next year. 📅 I also think about my family. 👨‍👩‍👧‍👦 I want to preserve the product of my work and pass it forward in a form that doesn't depend entirely on the promises of an institution or government staying intact for generations. So if Bitcoin's price disappointed me for the next five years, would my reason for owning it change? No. 🚫 I wouldn't enjoy watching the price go nowhere. But if Bitcoin kept producing blocks ⛏️, stayed decentralized, held its monetary rules, and let me hold, transfer, and program value without permission — then the reason I bought it would still be there. 📊 Price is what the market says Bitcoin is worth today. 🔒 The properties of Bitcoin are why I own it.

I built a 2-of-3 multisig wallet. Did everything right. Felt like a genius. Then I made the mistake most people make. I didn't test it. Years later I opened the wallet. Had my keys. Had 2 of the 3. Entered everything correctly. Zero balance. The keys were right. The setup was right. But the wallet software had silently changed something underneath me — the derivation path. Your seed creates addresses using a hidden "address map". When the wallet updated, it started looking at a different map. My coins were still there. The wallet just couldn't see them anymore. Right key. Wrong door. I got lucky — I had saved the old path and recovered everything. Most people wouldn't have. Now Morgan Stanley wants to "help" by holding your Bitcoin for you. Custody, trading, lending — the full package. Translation: they want your keys. If you're serious about self-custody, multisig is the real move. But if you set it up wrong and don't maintain it, it's just a more complicated way to lose your Bitcoin. I put together 6 rules that would have saved me from that panic. Plus when multisig actually makes sense vs a strong single-sig setup. Please let me know if you want the 6 rules.

If you follow the rules that wallets already enforce. There’s a lot of noise around “quantum computers breaking Bitcoin.” The reality is more boring (and more reassuring): 👉 Bitcoin remains quantum-safe if you use it correctly. Most risk only appears when users ignore best practices. The two big rules 👇 -------------------------------- 1️⃣ Never reuse addresses after you spend from them - Once an address is spent from, its public key is revealed on-chain - Reusing that same address again could expose it to future quantum attacks - Modern wallets already generate a fresh address every time — let them Rule: ✅ Receive → Spend → Never reuse that address again 2️⃣ Never give out your xpub (extended public key) unless you fully understand why - An xpub allows someone to: - If someone asks for it casually, that’s a red flag 🚩 Best practice: ----------------------- - Only use xpubs for dedicated payment systems - Create a separate wallet with: - Never mix it with your long-term savings wallet If you don’t know what an xpub is — that’s fine. Just know there’s no reason to share it unless you’re intentionally running a payment setup. The takeaway 🧠 --------------------------- Bitcoin doesn’t fail because of quantum computers. Bitcoin fails when users reuse addresses, overshare keys, or mix wallets improperly. Follow wallet defaults. Segregate roles. Don’t leak information. That’s it.

If you're using a cold card to secure your bitcoin, you should transfer all of your bitcoin out of your cold card wallet ASAP. A lot of btc has been swiped recently from peoples cold cards. You can read all about it on X/twitter. Here's what I would do right now if using the cold card: Step 1: Transfer all BTC from coldcard onto an exchange (Binance, Kraken, Coinbase, etc.) right now. Note: I normally NEVER encourage you to keep your btc on an exchange, but for the next few days it's a safer option than keeping it on a cold card. Step 2: Order a new type of hardware wallet, like a Blockstream Jade. Step 3: While you wait for your new wallet to arrive, watch a few YT vids to learn how to use it. Step 4: As soon as it arrives, use the dice roll method + add a BIP-39 passphrase to it. Step 5: Transfer your BTC from the exchange to your new hardware wallet. Step 6: Consider a multi sig approach for long term safety. Best, T
