I started thinking about investing/trading in 2022, not limited to cryptocurrency, not positioning myself in the cryptocurrency circle, but in the financial market, where all financial targets can be traded. Many people's problem is that they only focus on one market, A-shares investors only focus on A-shares, and cryptocurrency investors only focus on cryptocurrencies. When a market is not working, they become frustrated. Cross market traders are trading robots without emotions and beliefs. Without this trouble, they can fish wherever the fish are big.
