It's kind of absurd the level of failure in crypto lending. Putting aside anyone with criticisms of all things crypto these should all be based on the very basic and long established business model of taking deposits, making loans, and paying interest. There shouldn't be anything inherently difficult or "scammy" in that and it should be a successful business pillar in the crypto space. Besides the basic business your two other main priorities should be risk mitigation and dealing with liquidity issues. Surely long term some well run company ought to be able to sort this out.
