Is There a Digital Money That Will Succeed?

When we have another kind of crash like 2008, the world is going to look for a digital money. I don't believe it's going to be the current 21 million unit capped Bitcoin. And so something else will probably rise up that does have some sort of built in inflationary measure to the supply. If Bitcoin grew like gold grows, it would be 316 million Bitcoins by 2041. Wow.
