Evaluating only Nuri (formerly Bitwala)’s profile at its peak — without knowing the outcome — the model ranked Competition as the #1 likely cause. Documented cause: Market collapse.
Nuri (rebranded from Bitwala in 2021) offered a German IBAN account with integrated Bitcoin and Ethereum investing. At peak, it had 500,000 users storing €500M+ in crypto assets. When the crypto market collapsed in 2022, user deposits evaporated and Nuri's DeFi product (through Celsius Network) froze — Celsius itself went bankrupt in July 2022. Nuri filed for insolvency in August 2022, a direct casualty of the cascading crypto collapse.
Lesson
“In DeFi, your risk is not just your own product — it's the risk of every protocol you plug into. Cascading counterparty failure is a feature of the system, not a bug.”
