I won't consider you buying that fund. Because that's your problem. I don't know which fund can make money, but the choice can only be given to you. But I can give you some advice.
First of all, you refer to the relationship between fund net worth and profitability. Generally speaking, the net value of the fund has nothing to do with whether he can make money in the future. The net value can be simply understood as the money in the fund's hand now. You can simply think that low net worth is not good for your investment, only bad. Therefore, the risk of chasing high net worth in the fund is less than that of chasing low net worth. So I recommend you to buy a high net worth one.
And your question is not only about net worth, but also about overseas investment and domestic investment. This question is actually very simple. The risk of overseas investment is much higher than that of domestic investment. On the one hand, QDII has been losing money since its appearance. On the other hand, as far as the global economic situation is concerned, China is far better than foreign countries.
Perhaps you have found that the risk of buying low net worth is high, and the risk of buying overseas is high. Then you buy low-net-worth overseas funds ... the answer is self-evident.
The above is just my personal opinion, which does not represent anyone and does not encourage you to buy or not.
