To be honest I don't think the skeptical people thought bitcoin's success was probable and that's why they didn't bet on it. It's not really anything to do with them being content with what they have.

But it could be this too in some cases.

Some people do things unless they find a reason not to but so a skeptical person will only do things if they find a reason.

People who really feel they have enough might not see any reason to spend their time or effort placing bets, even on things they think are probable. But I don't think many people think that way.
