The spot bitcoin ETF was first approved, attracting more attention. 2. Before the approval of the US spot ETF, the BTC ETP market was larger than ETH. 3. The lack of collateral makes ETH ETFs relatively unattractive. 4. BTC is more relevant as a financial asset, while ETH places more emphasis on DAPPs and on-chain applications.
