John turned me on to Layerzwallet this morning. They have a good list of different Bitcoin layers/sidechains they want to support. There are a few varieties of BTC -> XMR atomic swaps. Improvements in monero scripting to make it easier are forthcoming. More and more LN wallets are parking sats in Liquid to improve UX. Its not terribly difficult to build atomic swaps to LTC or ZEC if there's demand for it. theyre basically BTC anyway. and yeah, you can store your wealth in the chain with the highest hash if you want. its all #Bitcoin man, I'm not joking.
