Some of them belong to futures companies ... but if they are stable profits, they are not reliable, and professional futures companies will not guarantee profits. Futures companies can give you some professional guidance and market advice, but they won't say stable profit, because the futures market is risky, so you'd better not be fooled. Regular futures companies, such as Everbright Futures Company under Huijin, only serve customers. You should be careful.

I wish you a happy investment!
