I'm new here so I don't want to come on an offensive.
But its clear that cardano isn't a capable chain to actually do anything.

Others have mentioned Monero which, personally I believe to be superior to BTC for many reasons among them being superior architecture (XMR is private and fungible) along with more decentralized due to POW being asic resistant (though who knows if they can keep that up forever)

With that being said one I would like to add to the list is Kadena ($KDA)
Very similar to BTC but more scalable along with being one of the top (if not the best) smart contract platforms.
