你买游戏币去哪里买?用英文怎么说?

你的问题有点不太明确，我估计你的意思可能是以下之一：

1）你是问他一般在哪里买游戏币？
Where do you buy the game coins? 你在哪里买游戏币？
Where do you usually buy the game coins? 你一般在哪里买游戏币? （估计最接近你的意思：你如果买游戏币，会在哪里买？）
2）还是他现在有的游戏币在哪里买的？
Where did you buy the game coins? 你在哪里买的游戏币？

Where do you buy the game coin to go to buy

国外的人是讲token的
