The limited supply of bitcoin is one of its biggest characteristics which assures the investors of the future. After the remaining bitcoin has been acquired, it all goes into the hands of investors. By that time, bitcoin will become a very scarce commodity and just like the usual principle of scarcity, the price keeps going up. Individual HODLers could set the Market price and influence it's volatility. Recently, bitcoin whales have been so intentional about draining all bitcoin into their wallets because they understand that the future belongs to bitcoin HODLers. If you have not started buying bitcoin enough, then do and hold for long, that's the only time you can be sure to participate in the future exploits.
Yes, the whales understand better how scarce it would be in future and how the scarcity would influence the price to go higher that's why they spend their time on buying it now than selling, anyone who's wise enough would join that path and acquire as much bitcoin as possible for the future so you won't be left out by then.
To prove your statement right, we've seen in the past how the price of Bitcoin skyrocket after the halving period, that's to say that it would be so in the future, well most of us won't be alive to witness what the price would be like in the next 100 years when all the Bitcoins has been mined but we can start now to make preparations by hodling to set a path of wealth through bitcoin for our future generations.
