1. Law:

After all, it is illegal.

Because China Industrial and Commercial Bureau has not approved any spot trading platform company so far. (Although there are 2,000 such small companies in Shanghai alone).

2. Mode:

In the long run, stocks are not a zero-sum game. As long as a company can generate profits, their share prices are growing because the company is getting bigger and bigger. And regular stocks will also generate dividends.

Compared with futures that are also zero-sum games:

Futures (Dalian Futures, Zhengzhou Futures and Shanghai Futures) are a game between investors, and the trading platform charges service fees.

Spot is an off-site model, which is a game between bookmakers and investors.
