If you had bought

10,000 RMB worth of Bitcoin 15 years ago

and just treated it as a game, holding it without selling

then even if it lost all value, it would only be 10,000 RMB

If you had this mindset

then today it would have turned into 30 billion RMB

Is there such a sage in the world?

I guess: the answer is no

So it's not that we can't make money, but that our mindset hasn't expanded!
