Citibank has identified a slowdown in ETF inflows and a weakening risk appetite as key factors behind the recent downturn in the cryptocurrency market. Despite strong stock market performance, cryptocurrencies have faced renewed pressure, exacerbated by a significant sell-off in October that eroded investor confidence. The October 10th liquidation event notably reduced the risk appetite among leveraged traders and new spot ETF investors, leading to withdrawals. The bank noted a marked decrease in inflows into U.S. spot Bitcoin ETFs, undermining a previously optimistic market outlook. On-chain data further reflects a cautious sentiment, with a decline in large Bitcoin holders, an increase in small retail wallets, and lower funding rates, suggesting long-term investors are selling and leverage demand is waning. Additionally, Bitcoin's breach of its 200-day moving average and tightening bank liquidity are seen as further suppressing demand. Citibank emphasizes that spot ETF fund flows remain a critical indicator of shifts in market sentiment.
