I completely agree that Bitcoin is very high-risk. Even if you respect its "dangers", you could still lose whatever you decided to risk.
Which is why you don't risk more than you can afford to lose. People in the Bitcoin community says these words over and over again.
Nonetheless, if you're ideologically sympathetic to Bitcoin, just because you don't risk more than you can afford to lose doesn't mean you don't risk anything. Most of us can afford to put in a few hundred, or (depending on net work) even a few thousand.
So I just want to clarify that my comments aren't designed to steer people away from Bitcoin. They're to remind people to be smart about getting into Bitcoin. It's still in the early prototype stage. You have to respect its dangers, or else there's this huge chance you'll lose whatever you decided to risk by getting into Bitcoin in the first place.
