#CryptoSecurity101 One of the most common questions concerns the security of cryptocurrencies and whether they are safer than regular money. It is often promised that the security of cryptocurrencies is quite strong, but news about cryptocurrency security indicates the opposite. Thefts occur in many different ways. All the largest thefts happened after cryptocurrency exchanges were hacked, including famous cases like Mt. Gox, with $350 million in Bitcoin stolen, and the Coincheck hack, with $400 million in NEM tokens stolen. The security of cryptocurrencies is also vulnerable within their own blockchain, with the best example being the event The Dao that led to the theft of $50 million in ETH. Thefts can also occur in more traditional ways, such as gaining access to a user's private wallet key, physically forcing the user to send funds to some account, or using various fraud schemes that cause users to lose their money.
