What do I do with Phantasma?

So, I've got myself some Phantasma tokens, but I'm not quite sure what to do with them. Can you help me out here? I'm new to the world of cryptocurrency and I'm trying to figure out the best way to utilize my investment. Is there a specific exchange where I can trade them? Are there any projects or platforms that accept Phantasma as payment? Or perhaps there are staking opportunities I can take advantage of? I'd really appreciate your guidance on this matter.
