Meme coins' extreme volatility poses limited systemic risk currently due to their small market share (~2-3% of total crypto cap) and minimal integration with regulated financial systems. Their speculative nature primarily impacts retail traders, unlike stablecoins or DeFi tokens tied to institutional leverage. However, risks escalate if memecoins gain mainstream adoption via ETFs or collateralized loans, creating contagion channels. Flash crashes could trigger margin calls on overexposed platforms (e.g., exchanges using memecoins as margin collateral) or erode confidence in crypto infrastructure. Systemic threats would mirror the 2022 Terra/LUNA collapse only if memecoins develop utility (e.g., payment ecosystems) while retaining hyper-volatility. Regulators now treat them as isolated gambling vectors, but interconnectedness via meme-adjacent projects (NFTs, SocialFi) warrants monitoring.
