According to TechFlow, on September 20, Cointelegraph reported that Ian Rogers, chief experience officer of hardware wallet manufacturer Ledger, emphasized the importance of maintaining security awareness during the bull market cycle in an interview at the Token2049 conference in Singapore. Rogers said: "In every bull market cycle, there are always some seemingly reasonable reasons to compromise on security or self-custody." He specifically mentioned that during the rapid expansion of the market, many cryptocurrency holders tend to store their assets in centralized exchanges rather than choose self-custody.

In this regard, Rogers stressed: "If you don't do self-custody, then what's the point of choosing cryptocurrency?" He warned investors not to rely too much on centralized exchanges, especially during market downturns, and cited the defunct cryptocurrency exchange FTX as an example. "All they did was give the funds to someone in the Bahamas and add a column of data on a spreadsheet. This is not called cryptocurrency, this is called fraud."

Beyond the cryptocurrency space, Rogers also noted that cybercrime is on the rise globally. “From now on, you can say every year that this is the worst year for cybercrime and it will be accurate,” he predicted. To combat this growing threat, Rogers recommends secure self-custody of digital assets through hardware solutions and clear signature technology, ensuring that users fully understand what transactions they are authorizing.
