If someone had bought just $8600 worth of Bitcoin in 2011, it would be worth $860 million today. Considering that the coins were moved to eight different wallets, it's possible the developers at the time split them among themselves.
In the stock market, when more people aim for short-term trading, prices tend to fluctuate. Companies don't like that, so they often offer generous shareholder perks to encourage long-term holding. Bitcoin is the opposite — since there are too many long-term holders, price fluctuations are relatively limited.
Money must always be in circulation. The weakening demand for Bitcoin is due to it being in a transitional phase before it is widely used for buying and selling goods in the real world. It will likely take some more time before it is not just held, but also used in everyday transactions.
