There’s so much uncertainty that it’s hard to know what is enough, even for modest goals, isn’t it? If bitcoin takes off, 3 BTC might put someone in the top 1%, or maybe there’s an unforeseen scenario that makes it worthless. For me, that’s where my faith in God comes in, and my ultimate hope in eternity. I will do the best I can to fulfill my responsibilities using the things that are in my control, but I will trust God for all the things that are beyond my control.
