Over the weekend, BTC slightly rose above 84k. It is said that BTC is now in an oversold state. Currently, it is the oversold period of the market. Oversold literally means that it has been sold too much. It is a feeling of a phenomenon. The phenomenon is a rapid decline in price, or a significant drop. Although there are some technical indicators like RSI to determine the oversold state, all technical indicators are lagging indicators of price. So, they are essentially useless. After you have diligently studied N technical analysis books, you might realize that returning to the basics, the main thing to grasp among all technical indicators is actually two indicators: one is price, and the other is trading volume. Apart from this, no matter how much general knowledge unrelated to specific assets you learn, it may not have much effect on investment success or failure. In other words, to hold BTC, the knowledge you need to master is 20% general financial investment knowledge and 80% specific knowledge about BTC itself. Do not get this reversed. Even if you have read numerous financial investment books, if you still treat BTC as a stock to speculate on, it is likely that you will not achieve significant results. Yet, almost 99% of people's understanding gets stuck at this level and cannot break through. Among them, there are even some prominent figures in the stock circle. In their eyes, BTC is just an asset allocation; if it outperforms the US stock market, allocate a little; if it does not outperform the US stock market, discard it like a worn-out shoe. While investment certainly needs to focus on returns, it cannot only focus on returns. Just as in business, one must certainly pay attention to income and profit, but cannot neglect national concerns and social voices.
