Last night was almost twelve o'clock, and I was eating skewers on the street with my old classmates who opened a restaurant. He opened his phone and showed me the reminder message from the supplier, saying that he couldn't bear it if this continued. At that moment, I was a little in a trance - I have been in the cryptocurrency industry for a long time, and the concept of "making money" seems to be completely out of touch with the real world. He couldn't sleep because of the payment of tens of thousands of yuan, and we were constantly discussing the rise and fall of a certain currency by dozens of points and the valuation of a certain project of tens of millions of dollars. Two worlds, the same word, completely different weights.
