A product post-mortem on growing CoinHold, EMCD's crypto savings product. Before any growth work, we spent ~6 months refactoring a legacy codebase that miscalculated accruals - you can't grow a deposit product on rails that break. The biggest lever was uniquely ours: auto-routing mining rewards straight into deposits, which moved active deposit share from 27% to 40% (an OKR I owned, 2x the target). A profit calculator and a full UX redesign lifted average deposit from $4,200 to $5,000. Then activation tactics hit diminishing returns.
