Hardware wallet manufacturer Ledger has sold over 7 million devices and currently manages about 20% of global crypto assets, valued at approximately $400 billion. As the price of Bitcoin rose from $68,000 to $98,000, Ledger's hardware sales increased threefold, and the transaction volume of its Ledger Live app surged 3.5 times. Ledger CEO Pascal Gauthier stated that the company is expanding from cryptocurrency security to a broader cybersecurity field. The Security Key app launched in September this year has entered the authentication market, which is expected to reach a market size of $40 billion by 2030.
