Elon is not a savior of Doge or Bitcoin, he uses you and other crypto users who are rooting for him to make money for himself. Did you see how did he pump and dump the Bitcoin and accept Bitcoin in Tesla and afterwards remove it and sell his Bitcoin? He is just using community to hype the Dogecoin and sell it at the top and you call that savior?
I agree with your opinion, that Elon is not using doge to increase in crypto development because till now he has not received doge in payment for Tesla purchase, so what Elon said about doge is being hype from over-speculating, so there is nothing to follow for any news elon tweet, just a waste of time in my opinion.
