Musk is just for Tesla and SpaceX. He has concerns over Bitcoin because of the greenhouse emissions emitted when mining Bitcoin. I think that is why he like DOGECOIN. Musk will not support Bitcoin for sure.
did he said anything to confirm this statement? I always thought he's just joking and trolling about Dogecoin. I still think he's not serious about it. he might have invested in dogecoin but for him throwing some million dollars is not a big deal. and this was a good investment for him considering if he invested in dogecoin at right time.
