I didn't know my address document is required for verifying the account. Should I give the document to Majormarkettrade? Is Majormarkettrade safe?

It is strongly recommended not to share any personal information with Majormarkettrade, an unlicensed trading platform.

Despite its claim of being based in the US, it is not registered with the National Futures Association (NFA), which is a clear indication of its illegitimacy in the financial market and the significant risks associated with it.

Individuals who interact with Majormarkettrade are at risk of financial losses or identity theft due to the platform's lack of regulatory oversight. It is prudent to avoid Majormarkettrade and opt for fully regulated brokers instead.
