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.
He just pumped the price of bitcoin but doesn't really contributed that much in bitcoin.
Maybe if we are talking about the Doge coin, he will qualify especially that he promotes it much more compared to bitcoin.
Manipulating a coin which is supposed to be a meme really helped him, especially that there are a lot of Doge coin investor due to his advertisements in Twitter and other social media platforms.
his tesla corporation put 1billion btc and after a while btc price shoots up to 48 to 49k usd from 38k . wasnt that enough ? i think that was more than enough . i never see a whale or a billionaire done that before . he promote btc more than doge because putting it in the bio is staple but tweets can be drag down .
