I am not so sure if Elon Musk is in it for the money! 
Do you think a guy with $150 + billion in the bank feels like he should get into crypto to earn some good money? He hasn't even started yet with Solarcity, Tesla, Spacex etc.
It's also very illogical if we start to think about it because Elon Musk is not a poor person who has to fight desperately in the crypto space, so it's very clear that he entered crypto just for fun while making additional profits.
