Because Elon musk understand the fundamentals of Doge, that was designed to be worthless, an anti-Bitcoin. He is trolling people who are too lazy to learn and understand. Elon who value knowledge and people with the will to learn. All that time, he was buying Bitcoin, not Doge! He was sending the losers followers toward the anti-Bitcoin and making fun of meme and social trends. I disagree with his behavior and attitudes to the mass. I believe in educating and seeding the root of passion for knowledge by offering to people an opportunity to understand why it matters. Even if 90% of the time, it's a waste of time. The 10% is worth all the efforts.
