#PI There's a viral joke online — if you bought 1000 yuan worth of Bitcoin in 2010 and held it until now, it would have turned into 10 billion yuan.

It sounds easy: "Just hold it, that's all."

But when you actually lay out the profit curve, you'll discover that the emotional journey of those 1000 BTC is completely unbearable for any human:

1000→1 million→30,000→5 million→80 million

Now ask yourself one more time: can you really hold pi coins?
