Is there any reason to actually own XLM?

Now granted I only have a slight knowledge about the uses of XLM due to the fact that I have been into cryptocurrency for no more than six or seven months and currently I’m only in the investing and accumulating stages.

But from my readings, a common thread is that people use XLM to transfer money from one exchange to another by converting a Crypto, say bitcoin, to XLM then sending the XLM to where they want it to go and then converting the XLM back into bitcoin. They do that because it is a more cost-effective way to transfer They are coins than in their native form.

It seems that the only time you realistically should purchase XLM is when you are wanting to move a different currency, am I correct in my understandings?
