Cardano has one big problem to legitimacy in my eyes. Why haven't the by the book US exchanges like Coinbase listed it? I'd bet that they are worried it doesn't pass the howey test so there could be issues in the future with the SEC. Nothing else makes sense to me, Coinbase has listed practically everything half decent. Doesn't mean it can't pump, but Cardano is potentially effectively XRP by stealth (founders effectively originally held entire supply and are just pumping and distributing it), but it won't actually be the next anything unless it clears the US regulatory hurdle.
