Is there any indication anywhere that they bought actual tangible Bitcoin?
"MicroStrategy...announced that it has purchased 21,454 bitcoins..."
Sounds like it to me, but who knows?
Lots of people started to froth when Paul Tudor Jones made his announcement but of course it was nothing but futures.
Institutional interest in BTC futures is nothing? Seems like a pretty big deal in terms of legitimacy, if nothing else. It would be silly to assume institutional traders are all going to jump balls deep into actual BTC custody.
