Spot Bitcoin ETF momentum is building strong momentum as we move into 2026. According to Bloomberg's senior commodity strategist Eric Balchunas, the inflows are arriving "like a lion" — a massive $1.2B streamed in over just a 48-hour window. This kind of capital velocity into Bitcoin spot ETFs signals serious institutional and retail appetite, suggesting the market is treating these vehicles as genuine alternatives to direct Bitcoin holdings. The two-day figure underscores how quickly sentiment can shift when adoption barriers drop. Worth watching whether this pace sustains or if we see consolidation.
