I think I am passed the point where I could sell my stash. The thought of not owning btc is horrible.
I think a 60-75% sell off is not too extreme. My real goal would be to be able to buy property etc with bitcoin in my area.
Although you guys can do what you want, I would really encourage you to think differently. First, selling even a half million $$ worth of bitcoin would incur a HUGE tax penalty right off the top. You took all the risk with your own money, so why would you give your tax agency 40% of all of your gains? It's free money you just gave them.
Secondly, yearly inflation is way higher than most govt's published figures. In the U.S. the actually yearly inflation rate is probably between 6-7%, with spikes in certain goods and services upwards of 9-10%/year. And inflation is rising globally and will continue to get worse and worse. Is your yearly income consistently increasing by that much every year to compensate for this? I highly doubt it. It would have to increase by that much at a minimum every single year until you retire (age 65) just to keep up. And the reality is that citizens' wages will continue to stay flat or even go down in the coming decades.
Bottom line, $500K fiat in 2020 will be only worth about $250K of purchasing power in 2035. So holding large amounts of fiat is ill advised. You want your purchasing power to stay flat or increase over time, not decrease. Holding bitcoin long term will beat the snot out of future inflation. Personally for me there is no "exit strategy", I will continue to buy and hold as long as Bitcoin is around, and only spend what I need to live day-to-day, month-to-month, etc.
And if you want to own a house or land, it would be smarter to only liquidate enough bitcoin for a sizable down payment, and then get a really good low fixed rate 30yr loan for the rest. Bitcoin's yearly returns would handily beat, actually crush any 3-4% yearly interest on the loan. Plus both the house/land AND your left over bitcoin would both be increasing in value relative to fiat while you were still making loan payments.
