Covered-Call Income
Hold an event-card basket, write a call against it, and collect the premium as income — the same mechanism as BlackRock's iShares Bitcoin Premium Income ETF, on our event-card indices. You keep the premium; your upside is capped at the strike. Auto-rolls each expiry.
A covered call requires a bull (long) event-card position to back it. Pick one you already hold — there is no naked writing.
Premium and yield are illustrative, computed live from the Black-Scholes price of the basket index — not a promised return. At expiry, if the index closes above the strike you forgo the upside above it; below the strike you keep the full premium.
