Their developers may work frantically to make the code work, sometimes accidentally leaving flaws that give hackers a foothold. Combined with the fact that a volatile market often leaves them suddenly holding a fortune, exchanges are a particularly ripe target for criminal hackers.

Exchanges often keep access to some of their cryptocurrencies in so-called cold wallets, which live safely offline. That means that if a hacker can gain access to a particular employee account — a common security breach on the internet — they can pull off a major heist, said Dave Jevans, the founder of CipherTrace, a company that tracks theft and fraud in cryptocurrencies.

If not, they often goes out of business. The company froze all customer transactions for three days before it allowed them to trade their money again. Or if they are hacked, they tend to be less likely to call for government help on ideological grounds, said Beth Bisbee, head of U.

MapleChange was a small, Canadian cryptocurrency exchange that began to see an uncommon spike in exchange activity starting in October.

As a result, MapleChange announced it was closing its doors for good. What made people suspicious was the immediate removal of the MapleChange website, social media accounts, and Discord and Telegram channels.
