If what you mean by "trading card" is the sell-buy strategy (trading) crypto/stocks to earn commissions:

➡️ You do not automatically receive a commission just for trading. But you can:

1. Becoming an affiliate of the trading platform (Binance, Tokocrypto, Bybit, etc):

You promote the referral link.

People register and trade using your link.

You can earn a commission from their transaction fees (up to 20%-50%).

2. Become an IB ( Introducing Broker ):

This is similar to an affiliate but more formal.

Usually for forex and crypto.

You guide clients, and earn commissions from their trading volume.

3. Open paid signal or education group:

You share analysis, buy/sell signals.

Get a commission from membership or fee.
