Who knows what’s going on with XLM?

I'd check the wallet compatibility issue before converting anything. XCN is an ERC-20 token, so the problem might be that your exchange or hardware wallet doesn't support the specific network or token setup you're using, rather than XCN being impossible to store in cold storage. I'd verify the supported networks on both sides and check the exchange's withdrawal options. If you decide to move it, make sure the network and address match before sending anything. I wouldn't swap to XLM just because it's easier to store without first deciding whether you actually want to hold XLM. You could end up paying conversion fees and taking on a different set of risks. Keeping it on an exchange also has its own custody risks. I'd figure out the storage issue first, then make the decision about which asset you want to hold separately.

XLM brother, XRP is my biggest holding too but XLM has won big this year with the DTCC tokenisation deal, Bermuda national economy going on chain on Stellar. So many more massive announcements this year, stellar XLM has really separated itself from XRP. XRP still my biggest holding too
