it is the same situation with all the altcoins that don't have fully anonymous transaction, which is practically 99% of them. you can always see their rich lists somewhere. for example https://chainz.cryptoid.info/ has lists of most of the altcoins and their richest addresses.
and it is always the same, some exchange or some developer who owns the coin and its premine or ICO or something like that. it is rarely and nearly never an individual who actually bought and holds all of the coins in one place and becomes a whale. whales usually don't stay in one altcoin!
