Ian Rogers, chief experience officer of hardware wallet manufacturer Ledger, emphasized the importance of maintaining security awareness during bull market cycles in an interview at the Token2049 conference in Singapore. He mentioned that during the period of rapid market expansion, many cryptocurrency holders tended to store their assets on centralized exchanges rather than choosing self-custody. In this regard, Rogers warned investors not to rely too much on centralized exchanges, especially during market downturns, and cited the defunct cryptocurrency exchange FTX as an example. In addition to the cryptocurrency field, Rogers also pointed out that global cybercrime is on the rise. To deal with this growing threat, Rogers recommends the use of hardware solutions and clear signature technology to achieve secure self-custody of digital assets, ensuring that users fully understand the transactions they are authorizing.
