How to earn TRX?

I'm really curious about how to earn TRX. Could you explain the steps involved in acquiring this cryptocurrency? I've heard about mining and trading, but I'm not quite sure how they work in practice. Could you also tell me about any reliable platforms or exchanges where I can buy TRX? And, if possible, could you provide some tips on how to maximize my earnings? I'm new to this, so any guidance you can offer would be greatly appreciated.
