Frequently Asked Questions (FAQ)
Q: Why did the crypto market drop 7.55% in one week?
A: The decline was primarily due to profit-taking after strong Q1 gains, combined with macroeconomic concerns and regulatory warnings in major economies like Turkey and China.
Q: How can Ethereum rise while Bitcoin falls?
A: Ethereum benefits from continuous utility growth in DeFi, NFTs, and enterprise adoption. Its value proposition extends beyond store-of-value narratives that dominate BTC discourse.
Q: What does “mining pool centralization” mean for Bitcoin?
A: With the top 10 pools controlling over 93% of hash power, there are theoretical risks to decentralization. However, no single entity holds majority control, preserving network security for now.
Q: Is it safe to participate in new token sales?
A: Always conduct due diligence. Check team credibility, audit reports, tokenomics, and community engagement before investing in early-stage projects.
Q: How do stablecoins impact market cap calculations?
A: Stablecoins like USDT and USDC contribute to trading volume and liquidity but have minimal price volatility. Their market cap remains relatively flat compared to speculative assets.
Q: What role do public chains play in crypto’s future?
A: Public chains form the foundation of Web3 applications. Innovations in scalability (e.g., Polygon), privacy (e.g., Oasis), and interoperability (e.g., Polkadot) will drive next-gen dApp growth.
