At present, China A shares are the most promising in the global market. Buying funds in the domestic market should be better than buying funds in overseas markets.
Of course, although the fund investment is a long-term investment, it does not mean that we will leave it alone for a few years after buying it, which will lead to big losses. Everything has fallen by 60% in one year, such as stocks or overseas high-risk investments like you. If it falls to a certain extent, you must sell it decisively, and don't expect it to rise back. There is little hope. If it really loses money like that, it usually takes at least two years to recover its capital.
For example, if you lose 50% in 1 year, you have to increase the annual rate of return to 100% before you can recover your capital. Because the base is different, 1 yuan first becomes 0.5 and then doubles.
