$BTC According to the report by Deep Tide TechFlow, on May 14, Glassnode data showed that the 7-day moving average of Bitcoin Delta spot trading volume turned positive, reaching a local maximum of about 5 billion dollars. The analysis indicates that while ETF fund flows suggest short-term profit-taking, spot accumulation and large fund inflows are pushing the price upward. Market sentiment is cautiously optimistic, with virtually no FOMO phenomenon among retail investors, indicating that this round of growth has not yet entered the overbought zone.
