After I sell all my holdings, I still can't help but repeatedly check its ups and downs,

I finally understand,
Why some people keep spying on their ex's life after breaking up.
When I just sold it, it soared all the way up,
I finally understand,
Why some people can't stand seeing their ex doing well after a breakup.
When I heavily invest in a coin, my emotions are completely driven by its fluctuations,
I finally understand,
Why it's said that love shouldn't be too full; excess will turn into backlash.
When I like a coin but haven't bought it yet, it suddenly skyrockets,
I finally understand,
Why some people regret missing their white moonlight for a lifetime.
