Can the future bitcoiners learn from the mistakes of others? Maybe if we can help educate them.
I think this is a valid point.
I think the scammer tag is a super way to educate.
It's an arms race though. Future scammers will also learn from the mistakes of others. Thus making it harder and harder to detect.
Furthermore, where does one draw the line between a scam and some business that was legitimate but failed no matter how spectacularly? In my mind the only difference is the original intent, which is both impossible to prove and irrelevant because the final outcome is the same.
The best course to take is to research who the heck you're giving your money to very thoroughly. Why do they want it? What are they doing with it? Why couldn't you do the same thing?
In otherwords, "Trust but verify!"
