Most of that “liquidity” is this token valued at its own price. Only $0.00 of real USDC is in the pool — that's all sellers can exit into.
Can you get out?
Best case from $0.00 real USDC in the pool
Selling $1.0K would return at most $0.000506(100% lost to price impact). That is more than the pool holds: it cannot be sold in full.
Up to about $0.00 keeps the loss under 5%. Estimate for a constant-product pool; concentrated liquidity moves price more, so real exits can be worse. Not financial advice.
