    • I trade across 3 exchanges and kept losing track of my real P&L, so I built my own trading journal, looking for ideas. May 30, 2026
      I trade mostly BTC across OKX, Bybit and Pionex, and I am constantly switching between apps and accounts was driving me crazy. Whenever I had profits I'd buy more BTC, then lose track of how much I bought, where I sent it, and what it was actually worth, it's a real pain. I tried using […]

    • What if we separated money from the state, abolished income tax, and based the entire economy on physical reality? Meet the Real Society. May 30, 2026
      We are currently facing a silent but acute crisis where our economic system has completely lost touch with reality. We live in a debt-driven society plagued by three fundamental, interconnected flaws: 1 Eroded purchasing power and skyrocketing wealth gaps. Over the past decades, fiat currencies have lost the vast majority of their value due to […]

    • Bitcoin Fixes the Incentives: Turning Compulsive Gamblers into Compulsive Savers May 29, 2026
      Brendan Sorsby’s most recent betting scandal that has rocked the college sports world is an indictment of fiat and our modern culture more than anyone thinks. To give a bit of background for the Bitcoin community: the transfer from Cincinnati, QB Brendan Sorsby, was due to make a massive 4 to 5 million dollars this […]
    • Doubting about my plan May 29, 2026
      I bought a large lump sum of IBIT in a registered account because I wanted Bitcoin exposure with tax advantages. I now realize there are trade-offs: I don’t hold the underlying asset directly, there are management fees, and I ended up buying near a market peak. With the subsequent drawdown, roughly 25%–30% of my portfolio […]

    • I knew better. I still sold near the bottom. May 29, 2026
      When FTX collapsed, I genuinely thought Bitcoin might be finished. Not just another bear market. I mean finished. Regulation, contagion, trust destroyed. I sold most of my position somewhere around $16k telling myself I was being rational. Six months later I was buying back above $25k. The thing that bothers me most isn't the money. […]
    • BlackRock Clients Sold 0.3% of Their Bitcoin Holdings Yesterday Why the Panic is a Massive Overreaction May 29, 2026
      Yesterday's institutional outflow data showed BlackRock's IBIT shedding roughly 2,424 BTC (around $178M). Most mainstream headlines are immediately reading this as a bearish signal, but digging into the raw numbers tells a completely different story. ​Context matters, and BlackRock’s total Bitcoin exposure is still absolutely massive: ​IBIT still holds roughly 792,000 BTC (valued at over […]

    • Unexpected dump? May 29, 2026
      I know we're still in the bear market, but timewise this is quite an unexpected dump in the last days, right? 12% in the last 2 weeks. No real macro indicators, positive news on war, stocks are flying worldwide. Is everyone fleeing into stocks? BTC too risky all of a sudden? submitted by /u/Electrical-Value-673 [link] […]
    • The people in charge of Bitcoin May 29, 2026
      Bitcoin has no boss. No foundation that votes on changes, no CEO who decides the roadmap, no shareholders' meeting, no token-holder vote. But the protocol does evolve. Slowly, contentiously, through a process nobody designed but everybody recognizes. Five stakeholder groups hold the real power — not by decree, but by veto. Any one of them […]
    • Collision Protocol: 1000 BTC Challenge Pool (#135, 13.5 BTC) May 29, 2026
