OKX 正在举办世界杯赛事，奖池是加密货币领域最丰厚的奖池之一。用户需要为他们铸造的每个 NFT 投入 10 USDT，并且每个钱包最多可以铸造 3 个 NFT（总共 30 USDT）使用 OKX 移动应用程序。通过持有获胜足球队的 NFT，所有 NFT 持有者都在分享奖池奖励。质押资金将在世界杯结束后连同奖池奖励一起领取。
结论：虽然 NFT 可以免费铸造，但交易费用大约为 10 美元，并且需要 30 USDT 的质押（总共 40 美元）。不建议创建多个帐户或钱包——尤其是使用同一设备——来铸造免费的 NFT，因为 OKX 实施了反欺诈政策以防止作弊。或者，您可以在二级市场上购买额外的 NFT。

结论：有一系列任务要做——主要是关注 Twitter 页面并加入 Discord——以赚取游戏内预测代币。奖池丰厚，参与游戏无需任何费用；但是，我在尝试领取免费令牌时多次遇到错误。不过，您可以尝试四处导航，只有在错误仍然存在时才退出游戏。
