这玩意儿我们也看不明白，汇率跟过山车似的。暴涨暴跌是常有的事，要炒比特币，玩得可不是心跳，而是心惊肉跳！不过我还是很看好比特币的，未来的价值难以想象。你想嘛，总量固定而且可以全球交易，比黄金还要稀缺。

We don't really understand this thingy at all. The exchange rate is like a roller coaster. Incredible gains and losses are a common thing. If you want to play the market in Bitcoins, it won't just make your heart race, it'll have you trembling with surprise! However, I still think Bitcoin is a good thing, and it's future value is difficult to predict. Think about it. There's a fixed amount of it and it can be exchanged around the world. That makes it rarer than gold.
