PANews reported on February 21 that 10 Research published an article on the X platform stating that the current crypto market structure is changing. While altcoins remain generally fragile and Bitcoin is in oversold territory, market positioning in crypto stocks and some selected altcoins is quietly shifting, with some assets beginning to outperform. Optimism (OP) is under pressure, with OP-USDT currently falling below its 7-day and 30-day moving averages, indicating a bearish technical outlook. It has fallen 24.4% in the past week. Furthermore, the Base blockchain is gradually separating from the OP Stack, signifying the end of their previous revenue-sharing partnership. Optimism has officially launched its first monthly token buyback program, committing to using 50% of its remaining Superchain revenue to buy back OP on the open market. The liquidity staking protocol ether.fi has migrated all its non-custodial business to the OP mainnet to leverage its enterprise-level scalability and provide some fundamental support for OP.
