Rising leverage in the Bitcoin market adds to the risk of a near-term pullback.

The broader implications of ETF adoption extend beyond price action.

While ETFs have mainstreamed Bitcoin in traditional finance, challenges remain. Regulatory scrutiny, custody risks, and fee adjustments could disrupt the current inflow trajectory. Moreover, the interplay between ETF flows and leverage-driven volatility suggests that Bitcoin's price path may remain unpredictable in the short term. Market participants must balance the tailwinds of institutional adoption with the headwinds of overleveraged positions.
