[Tuttle Submits Single-Stock Crypto Blast ETF Application] Tuttle has submitted multiple applications for single-stock Crypto Blast ETFs. According to Bloomberg Senior ETF Analyst Eric Balchunas, these ETFs plan to use a bearish options spread strategy to operate on the target stocks, while investing the cash portion not used for margin in cryptocurrency ETFs tracking Bitcoin (BTC), Ethereum (ETH), and Solana (SOL), aiming to achieve high-yield 'explosive' effects.
