This performance marks the fourth consecutive week of growth for the fund, which launched in late August.

Bitcoin ETFs saw a volatile period, recording a weekly net inflow of only $6.2 million, the lowest figure in 141 weeks of trading.

Hyperliquid recorded $3.1 million in inflows, recovering from previous losses. Meanwhile, BNB and Polkadot saw no activity, and several other altcoins collectively drew less than $4.8 million.
