stop blaming craptopia, these airdrops definitly sucks, i dont know why so many people are "happy" to have more coins if the price go down and down, i prefer having 100coins at 25/30$ than 107coins at 10$.
This is exactly why people are selling. Smartest people understand that if you receive 7% and you lose 20% you are in loss, the others are actually who in future will be called bagholder probably. But this is how the market works.. people who believe in the project will buy, people who don't believe in it will sell. Maybe bitcore will be successfull in future, maybe not, but always remember that until you sell, you earnt zero.
