"Don't buy a house, don't buy a car, don't get married, all in on tech stocks/Bitcoin": Essentially, it's giving up life's certainty, going all in on the highest odds in the era! In 2016, this timing was the perfect window for Sun's logic: at that time, the housing prices in first-tier Chinese cities had completed their main upward wave, and the subsequent 10-year annualized growth far lagged behind Bitcoin and leading tech stocks in the US stock market. Buying a house, a car, getting married and having children, fundamentally locks young people's most valuable cash flow, energy, and risk preferences into the "low liquidity, low growth, strong constraints" life standard—mortgages make you afraid to resign, afraid to start a business, afraid to touch high-volatility assets; family and children naturally make you risk-averse, prioritize stability, and completely miss out on high-odds get-rich-quick opportunities.
