Hello hello just downloaded the application but I don't know how to use it

Hello, I am new to Binance. Honestly, I do not really understand how it works. But I am interested in learning.

I have invested $20, I bought the main coins like BTC which has given me better performance in the SPOT wallet.

But I have also had losses, for example, when I invested in MIRA $5 and it went down losing $1.50.

The only way I have generated some money was by waiting until my coin generates cents, I transfer it to the FUNDS wallet and that way I accumulate every time I can.

Can someone tell me if that is okay?, or can you explain to a novice like me how to generate greater profit.
