4. Fans of reposting fakes follow a certain logic
A person is much more willing to share dubious and unverified information if he is convinced that a lie will become true in the future. In a sense, we are hostages to our own tendency to think ahead.

The mechanism is similar to the one that is typical for gamers: by investing in crypto, a person is ready for high risks and even sacrifices. Observation have described researchers from the Queensland University of Technology (Australia). Just do not draw the opposite conclusion: if your friend uses bitcoin, this does not mean at all that he is a sadist.
