One theory that the U.S. Justice Department is reportedly looking into is that the digital coin Tether (which is supposedly pegged to the U.S. dollar to make for a less volatile cryptocurrency) was used to manipulate the bitcoin market and cause a large run-up in price. This theory stems from an academic paper, which cast Tether in a very damning light. And it also led many to believe that the initial bitcoin craze was manufactured and destined to bust.

That’s why it’s important to only invest what you’re prepared to lose, and stick to more conventional investments for long-term wealth building.
