Today Bitcoin spike is huge as Elon Musk tweets. He is a billionaire and when such kind of personality talks about anything it gives big boost to them but I would say it's overall goods for cryptospace.
True, can't really be mad at him when he's bring this much to bitcoin or cryptocurrency in general. If I can say things to him in personal, I'd probably push him to promote bitcoin more and let the volume increase on exchanges like kucoin's LOL
