I don't have any evidence but I suspect it's technical people who got into Bitcoin early. Have a few million but no partner / no kids so maybe think they are "rich" and "set for life" so don't mind a gamble. Maybe the adrenelin of making all that easy cash is what they want to repeat. This would make sense because to hold Bitcoin for that long and not sell is kind of irrational gambling, even though the results have been good.
