Mineral'35

Own the market, not a story

A rules-based index of leading digital assets. Built the way long-horizon capital is actually managed — quietly, with caps, custody, and a calendar.

Capped weights

No single coin can run the book. Bitcoin and Ethereum lead; the rest of the sleeve represents the live market.

Trims and replacements happen on a calendar, not a headline. Emotions stay out of the allocation.

Underlying tokens sit with institutional custodians. You hold a claim on the index, not a hot wallet.

Illustrative sleeve. Actual weights move with the rebalance.
