I received unsolicited messages recommending 4xAi.

https://4xai.net/

It is strongly advised to avoid trading with 4xAi, a broker that may be fraudulent.

4xAi purports to be operated by Lighthouse Ventures LLC, allegedly registered with the Mwali International Services Authority (MISA). However, no records in the MISA database confirm this, casting doubt on the broker's licensing claims. 

Furthermore, the Belgian Financial Services and Markets Authority (FSMA) has included 4xAi on its warning list as a fraudulent operation in Belgium. Similarly, the Financial Conduct Authority (FCA) has also issued a warning against 4xAi.

Given the substantial risks, investors are strongly advised to avoid unlicensed brokers like 4xAi and to opt for fully regulated ones instead.
