Ideally I would like to 'cash out' when I have enough to be able to piddle around on my remote piece of property off the grid and not have to worry about food (and having to work a menial job for it) for the rest of my life. I don't want toys, cars, a second house or any of that. I want to do nothing but spend my time in the woods where i live now, grow my own food, relax and not have to worry about the future.
Basically, I don't need much. 'Cashing out' for me would be using the bitcoin proceeds to purchase a few generators, a few more solar panels, a second rifle for hunting, 50 truckloads of soil and manure, a shitload of seeds and bullets (fail safe investments if I ever heard of any!), etc. Then I would need enough to pay my monthly cell phone bill (yes, i live right on the cusp of cell service in the woods...and this is the only way i have internet), my yearly propane refill and my satellite porn. Then I'm happy. I've already backpacked around the whole world.
