Proof of Work. No pre-mine. Interoperability with any other chain thanks to Rosenbridge. The founder is one of the founders of CHAINLINK. Charles Hoskinson, Cardano's founder, said that it is the spiritual successor of Bitcoin.
But he said Bitcoin's proof of work should be abandoned and all Bitcoin user better move their bitcoins into some other networks, somehow.[1] Why does he support something that still uses Proof of Work?
Also, the Rosen Bridge seems barely usable, where is the interoperability? If this coin truly brings something novel toward cryptocurrency spaces, their team and communities should just simply prove it, not just merely compare and find similarities with Bitcoin.
