There is a power within compounding and exponentials... so if the BTC price is going up through the years, and maybe not very clearly over a few years, but over a cycle or two, you are able to see a kind of stablizing and building upon itself in such a way that after a certain passage of time, it becomes quite difficult to push the BTC price below certain price points.
With all the experiences you have shared, of course it is in accordance with what I said before, where holding BTC for a long period of time promises greater profits. Because it is based on several interesting things regarding the future development of Bitcoin, be it mass adoption or lots of positive news that can make Bitcoin prices rise significantly.
Even the history of previous years is always the center of our attention so that we don't repeat the same mistake of selling BTC and lamenting regrets when BTC touched $69k. In the coming years, we don't know how developments will occur, but historically we are in an era of quite good development and this will continue from year to year.
