“Crypto” the novel by Dan Brown

Even though it has little to do with cryptocurrencies, I found a strange analogy between the myth of Satoshi Nakamoto and Ensei Tankado, another Japanese character in the novel. One sentence struck me: "Tankado thought he wouldn't need money after he died, so why not give the world a little farewell gift?" Does anything come to mind? It's believed that Nakamoto is also dead, and with the invention of BTC and his wallet, he too is giving the world a gift. If anyone has read the novel and finds any similarities, I'd love to hear your interpretation.
