US-based Bitcoin (BTC) and Ethereum (ETH) spot ETFs are experiencing sustained positive momentum. On June 14th (local time), ETH spot ETFs saw a significant net inflow of $639.74 million, marking an eighth consecutive day of inflows. BlackRock's ETHA led the way with $510 million, followed by Fidelity's FETH at $56.94 million. Simultaneously, BTC spot ETFs also reported a net inflow of $230.55 million, continuing a seven-day streak. BlackRock's IBIT spearheaded this with a $520 million inflow. However, not all funds experienced gains, as FBTC saw a $110 million outflow and ARKB a $140 million outflow. This "double drag" of combined inflows, despite some individual fund outflows, suggests continued investor appetite for crypto exposure through regulated ETF products. Experts believe this sustained inflow could contribute to upward price pressure on both BTC and ETH. ```
