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 has nothing to do with BTC development, the biggest part he did was to invest in BTC and BTC exposure since he likes tweeting random stuff about crypto. Elon is a good figure and most crypto enthusiasts follow his twit. However, he trolls most of the time. We got a lot of good people in crypto who helped on BTC's development and exposure, they all deserve all the gratitude people are giving them.
