The answer is obvious, I think that there are DOGE coins in his investment portfolio and he fixes the increase in the value of these coins in order to fix the profit later. This is my opinion.
Because Elon Musk is one of the big investors in Dogecoin with a tweet he made positively arousing crypto the reason Elon musk posting a tweet is one way to make a coin lol that has no value is now a target for traders, Dogecoin, for me that is a very good thing in developing coins lol at this time elin is one of the coin generators that is considered up to an idea that deserves appreciation
whatever it is , now doge has pumped already so heavy , and for sure , nowdays , doge its no more than gamble game if u buy it, since it will explode anytime, i am not see any correction on doge . a billions dollar already injected to doge , which mean some whales over there waiting the right time for unload the bag.
