Are Bitcoin ATM's still a thing? There used to be one in a coffee shop near where I lived. If I deposited cash and wore a facemask and sunglasses, how would anyone ever know who did the transaction?
A couple months ago, I was incredulous when I noticed about a half dozen of them on google maps within a mile radius of where I am in San Jose. I haven't gone looking for them physically, though.
in reality, no, they don't know who I am. Back when LocalBitcoins.com facilitated face to face trades for cash around the world, you just had to have a high rating from previous transactions. Now... how safe do you feel showing up to meet an anonymous guy in a bar with thousands of dollars in Benjamins? That's the downside of being anonymous. /edit: The downside of operating completely outside the system.
/edit 2: I should also clarify that I never cashed out my casino's BTC in this manner. That obviously wouldn't make sense because anything that touched a casino wallet would be traceable to that nexus. I only used it to bring extra spending cash and rent money to countries where it was hard or expensive to transfer USD through banks.
It’s a pretty amusing crime plot in any case. If your goal is to find people to off who have money on them there are surely less complicated options.
