Hi all !
IMHO all alt coin is premine scam

Premine can be good, till a certain number. If the dev makes clear where the premine is used for and if it isn't a ridiculous amount you can safely say that it isn't a scam.
Then they should mine them themselves like everybody else, then they can choose to give them away or not. Pre-mining is unfair to the community and users regardless of what it's used for.
