i sure agree with cashing out every cycle but moving to a conservative investment such as dividends and bonds might not be easier for me. i speak for myself being a crypto investor, i have no idea which bonds and dividends but these are types of assets that you will have to give up all data while the assets aren't very liquid. vehicle is a depreciating asset which is a no-no. for some one like me who wants to reinvest in back, will just keep the asset in stablecoin and wait.
When you turn 65 or 70, which most of us still have a few decades to go, you can't, and shouldn't, be investing in a highly speculative and risky asset classes such as crypto (if even these assets will be around that far into the future, or become consolidated and stabilized in a few decades).
This kind of yo-yoing would get you killed in the market, and when you are 70 years old, you can't risk most of your investments in something that might kill the very investment you need in your retirement. You are not 25 or 30 and don't have 30 to 40 years to dig yourself out of a hole anymore.
