Your wife is right. In fact, less than 5% of stocks make money. Stock trading should have a good attitude and know the knowledge of capital market. Now you should not only care about the global stock market, foreign exchange, gold and oil, but also care about politics and war. Even so, you may not make money. You are not ready, and now you are particularly interested in the capital market. You'd better not touch them. Stocks don't always win. Judging from my financial difficulties, it is more suitable for an investment fund to make a fixed investment, just like a bank's lump-sum deposit and withdrawal, and the income is higher than that of bank deposits (you have to choose the right fund). If you are interested, you can communicate together. I have invested for several years, and the income is good.
