Charles Hoskinson, the creator of Cardano, has been vocal about his criticism of Ethereum Classic (ETC) and Ledger, a hardware wallet manufacturer.

Hoskinson believes that ETC is a deceitful project designed for insiders to mislead recruits with elusive aspirations. He sees Ergo as the manifestation of what ETC could have been.

Hoskinson also recently addressed the upgrade plans of Ledger, urging the cryptographic community to opt for wallets with open-source software that has undergone rigorous audits and emphasizing the importance of the smallest possible digital footprint and the incapability of updating firmware.

However, his rebuke of Ledger was underpinned by a fundamental belief about hardware wallets, which are primarily for personal funds security, not daily usage.
