Investors are closely watching the launch of the first Solana staking exchange-traded fund (ETF), a move expected to inject billions of dollars into Solana and the broader altcoin market. At least three altcoin ETFs are expected to launch later on Tuesday: Bitwise’s Solana (SOL) ETF and Canary’s Litecoin (LTC) and Hedera (HBAR) ETFs, according to Bloomberg analyst Eric Balchunas. The US Securities and Exchange Commission’s (SEC) approval of the first Solana staking ETF is a “transformative” milestone that may attract an additional $3 billion to $6 billion worth of new capital into the altcoin within the first year, according to Bitget exchange’s chief analyst, Ryan Lee. “Solana could now attract between $3–$6 billion in its first year.” The new ETF’s staking feature introduces an additional 5% passive income for its holders, a dynamic that may bring more institutional capital into the wider altcoin sector beyond just ETFs, added the analyst. Staking means locking your tokens into a proof-of-stake (PoS) blockchain network for a predetermined period to secure the network and earn passive income in exchange.

For Bitcoin (BTC), the ETFs accounted for about 75% of new investment when Bitcoin recaptured the $50,000 mark on Feb. 15, less than a month after spot BTC ETFs debuted on Jan. 11.
