Based on today's market data, Monday, May 4, 2026, Bitcoin (BTC) shows a predominantly bullish sentiment with several technical indicators signaling "Strong Buy".$BTC $ETH

Bitcoin today shows quite a positive development with prices approaching the range of $77,000 to $78,000. This increase is driven by growing investor interest, especially from large fund flows into crypto ETFs reaching billions of dollars. This trend indicates market confidence is beginning to recover after a decline period earlier in 2026. Additionally, the global crypto market capitalization has also increased significantly, showing a bullish momentum is forming again. However, Bitcoin still faces challenges at the resistance level around $79,000, so short-term movements may still be volatile. Over the past month, Bitcoin's price has risen more than 15%, reflecting a fairly strong recovery. Overall, today's condition shows an upward trend, but caution is still necessary because high volatility remains a main characteristic of the current crypto market. Solana Founder Warns AI Could Break Post-Quantum Cryptography Schemes Co-founder of Solana, Anatoly Yakovenko, considers artificial intelligence (AI) as the biggest threat in the near future to crypto asset cryptography. He states that AI could crack post-quantum cryptography (PQC) signature schemes before the industry strengthens its security. Bitcoin developers and analysts are now beginning to agree on the threat of quantum in the future without disrupting Satoshi Nakamoto's ownership. Yakovenko Pushes for Multisig Defense for Post-Quantum Cryptography Solana's co-founder believes that the industry has not fully understood the mathematical weaknesses or implementation issues of PQC. He wants wallets to combine several signature schemes with a two-out-of-three multisig system. This setup can be supported natively in the Solana transaction processor via Program Derived Addresses. “In my opinion, the biggest risk is that PQC signature schemes will be cracked by AI. We don't even know all the traps on the implementation side, let alone the mathematics,” Yakovenko said. Curve Finance founder, Michael Egorov, once asked whether formal verification could cover these vulnerabilities. However, according to Yakovenko, verification only helps if developers already know exactly what needs to be verified. He still prefers redundancy from two out of three independent schemes. Bitcoiners Reach Initial Consensus on Satoshi Coins Alex Thorn, head of research at Galaxy Digital, says there is a growing consensus regarding Satoshi's ownership. He cites several discussions held this week in Las Vegas with skeptics, supporters, and other Bitcoiners. Estimated 1.1 million Bitcoin BTCUSD owned by Satoshi are spread across approximately 22,000 P2PK addresses, each containing 50 BTC. Thorn revealed that long-range attacks would need to hack each address one by one. Meanwhile, exchanges could migrate to post-quantum addresses before the Q-day arrives. He added that the Bitcoin market can usually absorb selling pressure of more than one million BTC. This indicates the network can still withstand worst-case scenarios without sacrificing the core property rights of the network.

I have been engaged in margin trading for several years and I see that many beginners confuse isolated margin with cross margin. It is critically important to understand this because choosing between them can drastically change your results. Let's figure it out. Margin in crypto is essentially borrowed funds that you take from the exchange to increase your position. It sounds simple, but the devil is in the details. In isolated margin mode, you decide for yourself what portion of your capital to allocate to a specific trade. For example, you have 10 BTC. You borrow 2 BTC and open a long on Ethereum with 5:1 leverage. This means you are trading on 10 BTC (2 own + 8 borrowed). If ETH drops and the position is liquidated, you will lose at most these 2 BTC. The remaining 8 BTC stay untouched. That’s why it’s called isolated. Cross margin works differently. Here, your entire balance acts as collateral for all positions at once. Open a long on ETH and a short on Bitcoin simultaneously? All 10 BTC are used for both trades. If one position is in a loss and the other in a profit, the profit can offset the loss. The position stays open longer. But if both go against you, you can lose your entire balance. Examples will help. Suppose Bitcoin rises by 20%. With $5000 and no leverage, you get $1000 profit, which is 20% of your investment. But if you use 5:1 leverage, you trade on $25,000. With a 20% increase, profit is $5,000. After repaying the $20,000 loan, you have $10,000 — a 100% return. Nice, right? But when Bitcoin drops by 20%, with leverage you lose all $5,000. Margin in crypto is a tool that demands respect. Isolated margin gives you control. You know exactly the maximum loss on each trade. It’s convenient if you are confident in a specific position and want to limit risk. The downside is that you need to constantly monitor and manually add funds as liquidation approaches. This can be difficult for beginners. Cross margin is more suitable for experienced traders managing multiple positions simultaneously. The system automatically uses the free balance to prevent liquidation. But here’s the catch: it’s easy to overleverage and lose your entire account if the market moves against you. Personally, I use a combination of both modes. For example, if I am very confident in a certain altcoin — I allocate 30% of my portfolio to isolated margin. This limits my risk. The remaining 70% operates in cross margin, where I open hedging positions. If the main trade doesn’t work out, the hedges can help cover the losses. The key rule: margin in crypto is not a way to get rich quickly, but a tool for experienced traders. Cryptocurrency volatility is huge. The market can turn around in a second. If you are a beginner, it’s better to start with regular trading without leverage. Learn the market, understand how orders work, technical analysis, and risk management. When you switch to margin, start with small leverage and isolated margin. This will give you the opportunity to learn without risking losing your entire account. Gradually, if you are successful, you can experiment with cross margin and more complex strategies. Remember: margin trading can multiply your profits several times, but it can also wipe out your account. Always use stop-losses, never trade with your entire balance, and constantly update your knowledge. Good luck in the markets.
