Why haven't the couple of the fourth brother gone to Hong Kong these past two days?

Let's bring down a bit more, and push the costs to the minimum.

$PI Pi is different from the rest. It’s not meant for you to trade coins. On an exchange, it’s only a window that makes information public to everyone; its value isn’t reflected by the exchange’s trading price. It isn’t like building a building—towering heights rise from a flat foundation. It’s like planting a tree: the tree must first take root, and only after a certain number of rings can it bear fruit, and then peaches and plums will fill the world. So only people with vision quietly accumulate coins without making a sound. The train is running; barking dogs 🐕 are useless. This train keeps running all the way—when it arrives at the station, it will always pick up people with vision. Get on, get on—hurry up and get on. Let the dogs 🐕🐕 bark and howl, because the dogs can’t get onto the train.
