It has been discovered that OK has delisted USDT perpetual contracts, which means that in the future, only coin-margined futures will be available, or only perpetual contracts can be traded.

Second, it indicates that large funds with arbitrage and leverage needs are no longer trading on exchanges; the integration into traditional finance has been completed.

So, let us declare that the crypto world has moved from the Bronze Age into the Iron Age, one step closer to the cold reality.
