ZachXBT criticizes Ledger: Multiple privacy data breaches and exploitative fee-based practices.

According to Mars Finance, ZachXBT published an article stating that Ledger has been repeatedly hacked, resulting in the leakage of customer privacy data and targeted theft, causing losses of "millions of dollars." The article also points out problems with existing products (such as battery malfunctions in the Ledger Nano X) and questions whether Ledger's plan to IPO in the US after announcing a percentage fee for clear signing is an attempt to "maximize profits."
