According to Jason Fang (@JasonSoraVC) on Twitter, the proof of work (PoW) consensus mechanism continues to be fundamental for blockchain security and directly influences Bitcoin trading dynamics in 2025. Fang's recent post highlights the ongoing relevance of PoW, especially as miners compete for block rewards, impacting transaction speeds and network fees (source: Jason Fang on Twitter, May 29, 2025). Traders should monitor network hash rate and mining difficulty, as these metrics affect Bitcoin price volatility and overall crypto market sentiment. PoW-related developments often trigger rapid market movements and provide trading opportunities around key network updates or miner revenue shifts.
