Elon Musk? I don't think he qualifies. He has done nothing except buy some bitcoins. Putting "#bitcoin" in his twitter bio doesn't count as evangelizing.
Elon Musk only contributes with the fact that he is both popular and rich, which makes his tweets and bio on twitter about bitcoin a great impact to the BTC price. Nonetheless, it doesn't really dealt a huge change as he only started being active on shilling crypto on twitter the time that BTC already skyrocketing upon 20K price point. He would count as a contributor to the current price range of BTC with his 1.5B USD investment on Bitcoin and continuous endorsement on it.
