I have made https://mytestament.io/ To describe it: “Ever wondered what happens to all our digital memories, important information, and personal messages when we're gone? That's exactly the challenge I wanted to solve. MyTestament.io lets you securely store and designate digital inheritances - from heartfelt messages to important account information - to be shared with loved ones when the time comes.” It’s just been released, so technically it’s not yet made $500 , but the projections so far are for about that amount the first month.
