His ultimate aim may be to come up with his own coin, which may be named as MuskCoin or TeslaCoin. I also agree that it is not going to happen very immediately. He may wait for a few months, or even up to a year. During this time he will promote Dogecoin. And when the time comes, he will dump Dogecoin by giving some silly excuse and try to promote his own coin. But if you check the market caps of BTC and Doge, you can see that this plan hasn't worked very well. Doge market cap is still around 7% of that of Bitcoin.
That is what I said in the post you quoted yes,,, but I think instead of doing it publicly he will probably work with a few anon devs to launch new coins he will invest in to market but not directly say he is a part of.
He wants to protect his Tesla revolution and he may realize soon his crypto involvement is not good for the Tesla business. His investors and shareholders will be especially worrying.
He's probably dealing with a lot of money under our nose. I suspect that he already owned Bitcoin when he publicly announced that he's investing in cryptocurrency, in order to pump prices up for his own profit.
He's been manipulating the market for the past few months, there's a lot going on that isn't actually for the sake of crypto. I wouldn't be surprised if he starts his own coin either.
