option market making的意思|示意

The World Bank estimates the global market for virtual game goods is around $3 billion, making it an attractive option for gamers in less developed countries.

据世界银行估计，虚拟游戏商品的全球市场约为30亿美元，对于欠发达国家的玩家来说，这是一个充满吸引力的选择。

Of course, options market participants are already wise to this, and option premiums are high enough to deter many investors from making use of plain-vanilla volatility swaps.

当然，期权市场参与者对此很明智，期权定金很高足以阻止许多投资者利用单纯型选择权波动交换。
