There's also a podcast called A Death in Cryptoland about Quadriga, but I don't recommend it. A lot of the evidence they present is so thin it borders on conspiratorial. Maybe it was going somewhere but I gave up after 5 episodes when very little concrete information was presented.

I disagree. I learned a huge amount of information about Quadriga from that podcast (A Death in Cryptoland). It wasn't produced by some random Joe in his basement. It was produced by the CBC, Canada's public broadcaster and a Canadian federal Crown corporation.

When the producers of that podcast weren't sure about something, they said so. When they couldn't get an interview with a key player in the story (such as the wife), they said so.
