Wallets used by cryptocurrency exchanges are somewhat vulnerable to hacking. For instance, Japan-based Bitcoin exchange Mt. Gox shut down and declared bankruptcy a few years back after hackers systematically relieved it of more than $450 million in Bitcoin exchanged over its servers.
Meanwhile, there has been plenty of speculation that bitcoin’s big rise may have been due to a pump-and-dump scheme. 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.

In the wake of both Coincheck’s hack–as well as a big one that hit the South Korean exchange Coinrail–governments in East Asia began to crack down. Over the course of a few months, China, Japan, and South Korea all announced different measures to better regulate crypto-trading. The world was watching to see if this new technology would hit the mainstream–and government crackdowns following gigantic hacks helped poison the public perception.
