How scoring works →Summary
Ethereum Classic (ETC) is the original Ethereum chain that persisted after the 2016 DAO hack hard fork. It has suffered three documented 51% attacks totaling over $7M in double-spend losses (2019 and 2020), has minimal DeFi ecosystem depth (~$150K TVL), and faces unresolved governance controversy over the Olympia treasury proposal. Post-Merge hashrate improvements have raised the cost of attack substantially. Grayscale's ETCG trust is SEC-filed with ~$283M NAV. No explicit SEC/CFTC classification exists for ETC.
