Ledger hardware implant reignites Bitcoin ETF vs self-custody debate

The significance here is less the specific implant than the collision of two trust models: ETF custody outsources key risk to an institution, while hardware wallets outsource it to a supply chain. Neither is inherently safer, and the incident exposes how thin the evidence is for hardware wallets' security claims. The open question is whether the finding was isolated or points to a broader compromise, since the absence of scope details leaves the debate running on assumption rather than fact.
