A discussion has emerged within the cryptocurrency community emphasizing the importance of private key ownership for true control over digital assets. The phrase "Not your keys, not your coins" has been widely reiterated, underscoring that individuals do not fully own their cryptocurrency unless they hold their private keys. This principle has been highlighted as a critical safeguard against loss or theft, with some describing situations where users do not control their keys as tantamount to theft. Ledger, a prominent hardware wallet provider, reinforced this stance by stating that owning crypto requires owning the keys, advocating for self-custody to ensure asset security.
