According to monitoring by on-chain analyst Ai Yi, a wallet address is currently holding long positions in tech and semiconductor-related stocks worth about $19.78 million, with unrealized losses reaching roughly $5.24 million. About 10 minutes before the report, the address added 3 million USDC as margin in an apparent move to reduce liquidation risk rather than close the position. The tracked basket includes MRVL, SNDK, SKHX, MU, NBIS, CRCL, and ZHIPU. Among these names, only CRCL is directly tied to the crypto sector. The analyst also noted that the positions were opened near recent local highs, leaving the account more exposed to drawdowns following a pullback in the sector. The update highlights how on-chain observers are increasingly tracking cross-market leveraged positioning, especially when crypto-native capital moves into listed tech and semiconductor names.
