According to a report by Deep Tide TechFlow, on May 14, Glassnode data showed that the 7-day moving average of Bitcoin's spot trading volume delta turned positive, reaching a local high of about $5 billion yesterday. Analysis points out that although ETF fund flows indicate short-term profit-taking, spot accumulation and large capital have driven prices up. Market sentiment is cautiously bullish, with almost no retail FOMO phenomenon, indicating that this round of price increase has not yet entered the overbought range.
