A what‑if from the future

What if the SEC approves spot Solana and XRP ETFs?

Spot SOL and XRP ETF approvals broaden institutional access; the cleanest expression is altcoin beta (ETH/SOL) outrunning BTC, with MSTR and COIN as levered equity proxies. The direct rhyme is the Jan-2024 spot-BTC ETF launch and the Oct-2025 first SOL ETFs — 'buy the rumor' ran into post-launch profit-taking. Forward angle: with approval increasingly priced, the inflow-vs-expectation gap matters more than the headline — fade the knee-jerk pop if Day-1 flows disappoint.
