Since your family is not particularly well off, I suggest not to play. Pay gold. Sincere advice.
Speculation in foreign exchange and gold is very hot, and some people make money. But it must be remembered that high returns are necessarily high risks.
If you are skilled and well-off, you can support your husband by speculating in foreign exchange and gold.
However, it seems that your husband's skills are not in place. It is estimated that he rarely does simulations, and probably has no time or has never read some books on speculating in gold and foreign exchange. You can also watch others make money when your mind is hot, and then go to play.
Don't fight an uncertain battle. This is an old adage. You two communicate well, don't hurt your emotional communication, think about it, don't do it yet, do the technology well first, or quit completely. Personally, I suggest you give it up completely. Originally, investing in financial management was a good thing, but if it turned into speculation rather than investment, then forget it. Men sometimes have a better investment vision than women, but men's gambling may blind them. Communicate with your heart and wish you happiness.
