Op might wonder why there are too many untouched Bitcoins on different old addresses, it's given an earlier post answer, it could be the real owner can't access it or is stuck there because they are dead. I don't think there's a real long-term holder now, it might be a few of them, but the majority will sell Bitcoin in a short period of time when they see a small profit.

It's like a kind of Bitcoin graveyard on an address that can't be accessed anymore.
The Bitcoin is motionless and cannot be opened by anyone.
The initial holder must have sold his holdings and if any of them are able to withstand until now, of course he is very great and not tempted by the millions of dollars he can make.
Like Davinci Jeremie, a software developer from Chile who was an early Bitcoin holder who bought Bitcoin in 2011-2013 and still cost $1 at that time.
He can make $10m in just 10 years holding Bitcoin.
But some people also can't hold back too long and sell it at a very cheap price.
