$PI There’s no such thing as a good or bad coin—only a difference in *when* you get involved! Even the best coin is useless if you buy it at the mountaintop. Even a not-so-good coin, if you enter at the bottom, you can still get rich! Don’t blame this or that—blaming won’t help. Is π good or not? It depends on the price! If it’s 10 yuan, it’s trash; if it’s 1 cent, it’s a treasure! If you buy too high, that’s just your own foolishness—don’t blame the project team. The project team never called on you to buy!
