5000 yuan is not enough, at least it needs to be raised to 6000 yuan! You can open a futures account at present! Of course, it's not for me, it's not for customers, it's just 10 tons of soybean meal and rapeseed meal arbitrage! Lucky for you, the price difference between soybean meal and rapeseed meal in September is below that in 400 yuan, which is your best choice at present! Equivalent to picking up money! The stock market and futures market are the most formal markets! The other way is hard to say!
