Decision guide
Start with the question, not the product.
Borrowing against BTC and Bitcoin-linked dollars are different product jobs. Custody-model work is supporting research when your control setup is still the blocker.
How to use this guide
Choose borrowing only if you already know dollars against existing BTC is the real task.
Choose Bitcoin-linked dollars if the core issue is wrapper structure, redemption, or stable-value design.
Choose the control-model path if key control or recovery is still upstream of any product choice.
Choose the research path if you still need a framework before any category-specific workflow.
