Fascinating read on the darker side of the Bitcoin story. Many interesting stories on criminals that slipped up their opsec (often in very subtle ways) in combination with the financial trails in the Bitcoin blockchain.
I loved reading more about the inception story of chainalysis and the succes they had tracing payments back to criminals. The book read like a thriller in some sequences such as on the arrest of Ulbricht, getting set up with his laptop unlocked and unencrypted in a public cafe.
Also amazed at the operation bayonet, taking down alpha02, his unlocked laptop phone and alphanet servers, alongside the dutch initiative of taking over conrol of the hansa dark web marketplace.
