What would you do? Would you sell all your stash? Would you sell in the way to one million, or only when it reaches that price?
It's tough to answer right now. There are so many variables that might come into play that we don't think about right now, but will affect our long term game plan.
If Bitcoin ends up reaching prices near the $1 million level, it has probably shown enough strength and demand that I can't see it go back down much lower. I expect similar market behavior as what we see Gold go through. Just for diversification purposes, I will probably cash out 15% to fiat, and convert 25% to Gold. This leaves me with 60% Bitcoin which is perfectly fine with me.
I will never sell my entire stash. That's pretty pointless at a stage where it has become a serious enough asset being worth $1 million.
