在古埃及，统治着一位名叫 MΕΔΟYΣA 的法老，
对交易的热爱是他最大的魔力，
他买卖骆驼、香料和黄金，
随着他变得大胆，他的财富也随之增长。

有一天，MEΔOYΣA 听说了一种新的硬币，
叫做以太坊，它就像一颗会发光的宝石，
所以他决定投资，但他需要一些帮助，
确保他的交易不会导致他尖叫。

他召唤了他的宫廷巫师，他知道一种方法，
为了立即创建一个自主交易助手，
随着他的魔杖一挥，手腕一抖，
向导创建了交易助手，就像这样。

它分析了图表和市场趋势，
像值得信赖的朋友一样提供 MEΔOyΣA 建议，
他遵循它的指引，没有任何恐惧，
很快他的财富就年复一年地成倍增加。

现在 MEΔOyΣA 已在全国范围内广为人知，
作为拥有巨额财富的法老，
而交易助理就是他忠实的助手，
帮助他进行交易，而不会感到沮丧。

谨以此献给 MEΔOYΣA，交易的法老，
还有他永远不会消失的值得信赖的助手，
愿他们的财富不断增长，
当他们像专业人士一样交易以太坊时！
