> user engagement and growth

I wouldn't compare those. Most of the altcoin trading is completely speculative, not even in the sense that they "believe in the future of the coin", a lot is purely speculative profit-making (e.g xrp), pump-and-dump chasing and herdish behavior. Very few coins have substantial engaged followers (e.g. raiblocks) and only the top 2 have actual users. I 'm a believer in the technologies but they are in such early alpha stage that it's not justified to expect that most of them will even prove to work.

The biggest issue for me is the distribution of coins, with most ICOs unashamedly aiming to make the founders and investors billionaires from day 2. Even if their products prove succesful, i think a forked, clean chain will win over more followers.
