Where can I swap Avalanche?

Excuse me, I'm interested in cryptocurrency trading and I've heard a lot about Avalanche recently. Could you possibly tell me where exactly I can swap Avalanche? I've been looking around but haven't quite found a reliable platform yet. Is there a specific exchange or marketplace that you would recommend for swapping Avalanche? It would be great if you could point me in the right direction. I'm looking for a secure and user-friendly platform that offers competitive rates for swapping Avalanche. Thank you in advance for your help.
