I will divest gradually to usd if the bitcoin price bubbles, only to increase my btc holdings in the future. Probably pocket a small profit in usd to put a down payment on a house, then put the rest back in btc for the next run up(s) in the coming years. Hopefully it will get to the point I don't have to and can buy real estate, land, etc.. Without having to switch. I realize that's possible now in some places, but I'd like to see it everywhere.
