Do you trust his statement? I can understand if he is holding Bitcoin and Ethereum but not for holding Doge. Elon Musk isn't someone who wants to take a risk of his money by investing in Dogecoin. He should know very well that Dogecoin has nothing to survive a long time in crypto market. Even its price cannot increase if no Doge tweets are made by Elon Musk. Although he really has Doge, it may be several months ago, before he pumped Dogecoin.
