Large investors may not read posts on this forum, although even here I know 2 people who have more than 50 bitcoins. Also seen a few listings for yachts in this forum) So don't think that sitting here right poor)
50 bitcoins is not such a big amount and investors with so many bitcoins do not really want to leave. Yes, of course there are exceptions, but among my friends whom I know. They are in such a market, trying to keep their bitcoins.
