Suitcases of cash and/or gold have worked for even more ambitious goals
One must take cash out of a bank and then carry the suitcase to the other guy, meeting him in person and in private. Seems easy and safe to you?
Here, a few years ago, a State governor and a couple of Congressmen lost their posts and faced criminal charges because they were recorded by hidden cameras receiving packets of cash with the equivalent of 50'000--100'000 dollars. Another one was caught boarding a plane with a large sum stuffed in his underwear.
you can just fucking send a letter with a private key if you really really don't understand what Blockchain taint means.
I don't understand. If A puts the coins into some address X and sends its private key to B, the path on the blockchain just gets reduced to one node X and zero edges. With the exchange deposit and withdrawal logs, the two links from A's bank account to the coins on X and the two links from there to B's bank account can be traced. What am I missing here?
