There is no way 1% of 8 billions are stacking and holding their own keys at the moment. ~4 billions are not even online, let alone know about bitcoin. Considering that most buy the top and sell the bottom, this "dance" will continue for a while. Stability will come once maxis or similar will increase their positions in time. Also, because of the pseudoanonymous nature of the protocol, you can only count addresses at best (not actual people). Personally, I'd be shocked to hear that more than ~4 millions (that's 0.05%) are holding their own keys rn.
