Jensen Huang once publicly championed Ethereum and blockchain technology, calling them foundational computing forms during Nvidia earnings calls in 2017 and on CNBC in 2018. The company's gaming GPUs became the dominant hardware for Ethereum mining, but the 2018 crypto crash wiped over $20 billion off Nvidia's market cap in a single trading day after Q3 revenue guidance missed Wall Street forecasts by roughly $700 million, which Huang attributed to a prolonged "crypto hangover." Nvidia returned to the mining sector in 2021 with its dedicated Cryptocurrency Mining Processor (CMP) line, generating approximately $526 million across its product cycle, while simultaneously implementing LHR hash-rate restrictions on RTX 3060 cards to separate gamers from miners. Huang endorsed Ethereum's transition to Proof of Stake at Computex 2021, and when the Merge completed in September 2022, GPU mining demand collapsed overnight. By that point, Nvidia's data center business had already overtaken gaming as its core revenue driver, cushioning the impact. In March 2026, at NVIDIA GTC, Huang praised decentralized AI project Bittensor as a modern iteration of "Folding@home," triggering a 20% surge in the TAO token — a moment many observers noted echoed his earlier pro-crypto stances. As stablecoin-based payment rails like x402 gain traction for AI agent transactions, the intersection of AI and crypto remains an active frontier, though Huang is unlikely to revisit such commentary in his capacity as Nvidia CEO.
