I like them, but haven’t figured out how to store them in cold storage (well). Used to be big in Monero

Have you tried looking at the Exodus wallet? It's good for PC's - just install it on a USB stick and you're good to go. It's got about 30 cryptos you can exchange between, right there on the wallet - plus, you can store about 40 other coins on it, but you have to use another exchange to trade them from because Exodus does not have built-in tech for trading them.
