Well, there will be examples where you are correct. That does not mean every coin with premine or IPO is a scam, lol.
Yes ALL IPO/ICO coins are scammy.
They choose to distribute coins that way to get an unfair advantage(s)
I advise new user avoid them and..
- Ask who made it.
- And how many coins have they been involved with making before.
BEFORE SPENDING A PENNY !
If they can not answer those questions or if it's an IPO or ICO etc then avoid it period .
