Bitcoin traded around $86,183 on September 22, compared to $80,874 on September 18, and briefly climbed above $87,000, according to CoinGecko. The inflows occurred during a previously weaker period for fund flows, with Bitcoin ETFs seeing only about $6.2 million in net inflows the prior week.
Analysts cited risk-on sentiment, increased ETF demand, and short covering as reasons for the uptrend, as noted by The Block quoting Presto Research’s Min Jung.
