Difficult to believe that this guy will just buy that much. Trial version?

It is either he doesn't own 100-500 bitcoins or he doesn't have any.
Why exactly do you feel someone like Musk needs to own a considerable amount of BTC just because he is rich? He probably bought and sold BTC many times in the past and is simply talking about how much he owns currently.
3. he loves and believe in Tesla more than Bitcoin
This is pretty obvious. Do you really think that the founder of Tesla would prefer BTC over his own creation?
I don’t believe Musk only holds 0.25
BTC, there’s no way he has that small a stash. If he still has any then it will be a lot more than that, he’s a very clever guy, he knew what he was doing tweeting about bitcoin

He probably sold most of his stash in the past and is HODLING a small amount for now. Why does everyone think that him tweeting about BTC equates to him HODLING a large stash of BTC?
