Bitcoin, Ethereum and XRP take up around 80% of total market cap and I’ll class those as legitimate enough to fall in the non-scam category. I’ll also ballpark half of the remaining 20% as not being scams (I know that’s a little debatable too, is a poor business premise a scam for example?), and I’d say that’s not too bad on the whole.

If we’re talking about number of projects then I can’t disagree, there’d be no argument.
