Economist Henrik Zeberg remains optimistic about Bitcoin's potential for a Christmas rally, predicting it could surpass its all-time high of $108,200 despite a recent decline. However, he warns that this surge may be short-lived, with a potential drop to around $16,000 following the peak. Additionally, Zeberg anticipates a significant altcoin rally as Bitcoin dominance decreases, signaling a shift in market sentiment. Meanwhile, Bitcoin ETFs faced their largest single-day outflows, totaling $671.9 million, reflecting investor volatility.
