This kind of news does make you wonder whether the HODLers will keep their coins even if the price soars further. Those who were in early enough may be tempted if the price is so high that they could be rich just by selling or by taking profits. If that starts to occur, there's a risk of a fall in BTC's value when dumping takes place.
Another risk is that the new HODLers which make up that percentage are the ultra-rich like Elon Musk, who are capable of manipulating the market just through tweets and announcements.
