The escrow account was unlocked (smart contract) but Ripple is not going to sell like previous this amount of XRP to the market (OTC or programmatic sales). Pls, read the quarterly report.

"Given the reports of inflated volumes, which Ripple took seriously, the company temporarily paused programmatic sales and placed limits on institutional sales to evaluate the problem in early Q2. "


"Ripple decided to pull back from providing XRP over-the-counter at scale toward the end of Q2, in light of the OTC desks’ ability to source institutional demand for XRP in the open markets. Going forward, Ripple plans to focus institutional sales on markets where the on-exchange liquidity for XRP is insufficient to meet institutional demand."
