1 there is no margin system for paper and silver, and futures only need 5~ 15% margin. 2 Paper and silver have no leverage effect, while futures have leverage effect 10 to 20 times, which is risky. 3 paper silver can only be long, futures can be long, and 4 paper silver can also be short. At present, the starting point of ICBC's paper-banking business is 100. There are few investment channels for paper and silver. At present, only ICBC has launched paper and silver business, including account silver (ounces) against US dollars and account silver (grams) against RMB. Chuangyuan Futures Company sincerely answers your questions, thank you.
