The topic of college students is like this. From a moral perspective, it is not recommended to promote the cryptocurrency circle, especially contracts, to the elderly and young people. For the elderly, it's all retirement funds and money for medication. Young people have poor risk resistance and recognition abilities. But if I had children, I would teach them early on and let them experience speculation. The younger they are, the earlier they can understand it. If it's suitable for this industry, they can play. If it's not suitable, they won't lose much. It's much better than losing and becoming disabled in middle age. At that time, the cost of trial and error is too high. The cryptocurrency market is like a big cesspool. Speculators are fine, but most of the speculators are victims. There's nothing malicious about it, just to make some quick money. Practitioners are basically a group of prostitutes and scammers, expect them to have morality? Does Zhao Changpeng have morality? Does anyone have morality? Are these project developers ethical? Is it ethical to open plates and give out orders to dogs? These people left the mainland and went overseas, launching all kinds of brainless coins. They don't know that these coins are deceiving people? It's all about making money, so whether it's packaging it as web3 teaching or promoting contracts nakedly, it's all just a show to lure people into the water. That's all we're talking about. Do you have morals?
