Also in the top five were Dude Perfect ($20 million — €17.5 million), Daniel Middleton ($18.5 million — €16.2 million) and Jeffree Star ($18 million — €15.7 million).
The estimated figures — for the year to June 2018 — given by Forbes were before tax and fees for agents, managers and lawyers.
Despite Ryan's videos getting millions of daily views, just $1 million of the total came from advertising shown before videos, according to Forbes, with most of his revenue coming from sponsored posts.
