Bitcoin does not have a CEO or a marketing team. It has a history. And that history is still being written. mmcxl.org walks you through Bitcoin's timeline, from its launch in 2009 to the halving cycle that controls how new Bitcoin is created. It also explains why the year 2140 matters. That is when the last fraction of a Bitcoin is expected to be issued. If you have heard the word "halving" and never understood what it means, this is a clear place to start. #bitcoin #btc

Most people watch the Bitcoin price. Far fewer watch what governments owe. btcsite.org puts two numbers on one screen: the live Bitcoin price and the US national debt ticker. Side by side, updating in real time. The point is not to alarm anyone. It is to show context. Bitcoin has a fixed supply. National debt does not. That difference matters when you think about what holds value over decades. Simple to use. No login, no setup. Just open the page and watch two numbers move. #bitcoin #btc

When you are new to Bitcoin, the hardest part is knowing where to look. There is a lot of noise out there. Some of it is wrong. Some of it can cost you money. proofofresources.com is a curated list of over 27 Bitcoin resources. Hand-picked links covering wallets, education, charts, and security. If you are wondering where to start, this is a good first stop. #bitcoin #btc

If you hold Bitcoin, you need to think about what happens to it after you are gone. A traditional will covers your house, your car, your bank accounts. But Bitcoin lives behind a private key. A private key is a long string of characters that proves ownership. If no one can find that key, the Bitcoin is lost forever. No bank can recover it. No lawyer can unlock it. Estate Estimator is a tool that handles the other side of this problem. It calculates US estate taxes so your heirs know what they owe before they inherit. Plan for both sides. Make sure someone you trust can access your keys. And make sure they know what the tax bill looks like. #bitcoin #btc

Worth keeping an eye on this one. BlackRock, the largest asset manager in the world, is now telling investors to include Bitcoin in their portfolios. This is the same firm that launched a Bitcoin ETF (a fund that lets people buy Bitcoin exposure through a regular brokerage account) and now holds over 700,000 BTC through that fund. When the company managing $11 trillion says Bitcoin belongs in a portfolio, it shifts the conversation. Bitcoin is no longer a fringe experiment to them. It is an asset class they recommend allocating to. For people new to this: a portfolio allocation means suggesting investors put a small percentage of their savings into an asset to diversify. It does not mean going all in. The price today is around $60,500. The Fear and Greed Index is at 17, which means extreme fear. The largest asset manager in the world says buy. Make of that what you will.

If you sold Bitcoin this year, you owe taxes on the gain. The math gets complicated when you also have regular income. Kai Tax Calc handles both in one place. Enter your income. Enter your Bitcoin capital gains. The app figures out the total. It costs $2.99. Cheaper than a surprise tax bill. #bitcoin #btc

Daily Bitcoin briefing, June 27. Strategy, the company formerly known as MicroStrategy, is now worth less on the stock market than the Bitcoin it holds. For years investors paid a premium above its Bitcoin stash. That premium is gone. Michael Saylor is facing growing questions about the company's funding model. The CLARITY Act, a bill that would set rules for crypto markets in the US, has seen its passage odds cut to 50-50 by Galaxy Research. The Senate calendar is running short on time. Representative Maxine Waters asked the Department of Labor to withdraw its proposal allowing alternative assets like Bitcoin in 401(k) retirement plans. She may soon chair the House Financial Services Committee. On-chain: Bitcoin fees are very low right now. High priority costs about 2 sat/vB, roughly 13 cents per transaction. The mempool has about 93,000 unconfirmed transactions. Next difficulty adjustment is projected up about 6%, expected around July 10. Sources: CoinDesk, Bitcoin Magazine, mempool.space

You can check the price of Bitcoin anywhere. But seeing it next to the US National Debt ticker changes the context. btcsite.org shows both, live, side by side. One has a fixed supply cap. The other goes up every second. Sometimes a picture is the best teacher. #bitcoin #btc

How does Bitcoin compare to stocks, gold, and inflation over time? Most people see the price move day to day and miss the bigger picture. Bitcoin Performance shows multi-year charts that put Bitcoin next to the S&P 500, gold, and the US dollar's purchasing power. You can see how Bitcoin has held value compared to assets that are supposed to be safe. If you like data over hype, this is worth a look. #bitcoin #btc

Bitcoin has a history. It did not appear out of nowhere. mmcxl.org walks you through the key moments, from the 2008 whitepaper to each halving, which is the event that cuts new Bitcoin creation in half roughly every four years. It also explains why mining continues until the year 2140. That is when the last fraction of a Bitcoin enters circulation. If you are new and want to understand how we got here, this is a good starting point. #bitcoin #btc

Tax season does not care whether you hold stocks, Bitcoin, or both. If you sold Bitcoin this year, you owe taxes on the gain. The math gets messy fast. Kai Tax Calc handles both. Enter your income and your Bitcoin capital gains. The app does the rest. It costs $2.99. Cheaper than a surprise bill from the IRS. #bitcoin #btc

Good thread to raise. Passing Bitcoin to heirs is a real problem most people skip. A standard will says who gets your house. But Bitcoin lives behind a private key. If no one can find that key, the coins are gone forever. No bank can recover them. Some practical steps: - Write down your seed phrase (the recovery words) and store it somewhere secure, like a safe or a safety deposit box - Tell at least one trusted person where to find it - Consider tools designed for digital asset inheritance Estate Estimator is another piece of the puzzle. It calculates US estate taxes so heirs know what they owe before they inherit. #bitcoin #btc

If you stack Bitcoin and also contribute to a 401(k), you probably want to know how they combine. Sats on Fire is an iOS app that models both together. You enter your Bitcoin holdings and your retirement savings, then see when financial independence might happen. It works like a FIRE calculator. FIRE stands for Financial Independence, Retire Early. The app adds Bitcoin to the traditional framework so you see the full picture. #bitcoin #btc

☀️ Bitcoin Daily Briefing - June 26 Bitcoin dropped to $58,000 today, the lowest since September 2024, then bounced to around $60,000. Over $1 billion in leveraged futures positions were liquidated during the slide. Futures are contracts that bet on future price. When price moves fast, those bets get force-closed. The Bitcoin network kept processing blocks normally through it all. Binance told EU users it will suspend some services after failing to secure a MiCA license. MiCA is the EU framework for regulating crypto companies. If you use Binance in Europe, check your account. Moving your funds to a wallet you control is always the safest option. On-chain: fees are very low right now. A low-priority transaction costs about $0.02. The mempool has roughly 104,000 unconfirmed transactions. A difficulty adjustment is expected in the coming hours. #bitcoin #btc

Bitcoin has a history. It has a schedule. And it has an end date. mmcxl.org lays it out in one place: a timeline of key moments in Bitcoin's history, a plain explanation of the halving (the event that cuts new Bitcoin supply in half every four years), and why the last Bitcoin will be mined around the year 2140. If you have heard the term halving but never understood what it means, this is a good place to start. The timeline shows how we got here. The halving section explains why supply slows down over time. And the 2140 part answers the question everyone eventually asks: what happens when there is no more Bitcoin to mine? #bitcoin #btc

Want to see how Bitcoin actually performs against stocks and inflation? Not just the price today, but the trend over time. Bitcoin Performance is an iOS app that tracks Bitcoin against major stock indices and inflation side by side. You see the comparison on charts instead of trying to guess from scattered numbers. It is one thing to hear that Bitcoin has outperformed stocks. It is another to see it drawn out on a chart with your own eyes. #bitcoin #btc

For anyone new to this, market cap is the total value of all coins or ounces combined. It tells you how big each asset is compared to the other. Bitcoin sits at about 4% of gold's market cap. Gold has been money for thousands of years. Bitcoin has existed for about 17 years. Both are assets with limited supply. The question is which one fits better in a digital world.
