yeah it is a weird concept because it seems Federal Reserve like to just make money appear like that.
It will probably happen a couple more times and like you said it won't work again.
Clams did it before by saying if you had BTC or LTC between certain years then you would get Clams.
I think what would be interesting if someone had a good project and they did that but said a certain portion of the coins was going to holders of like 10 different cryptos. Then other portions would go to others.....etc. To get wide distribution and have people looking at the project.
