You are saying there was no of Trump family that knew about his Trump coin before it was launched that night? There was none of Trump family that knew about his melenia meme coin before it was launch? The thing, there is always an insider no matter what but because of security and exchange commission enforcement, they drastically reduce it but it's there till now but they share it on the low so they don't get exposed, this is why the rich keep getting richer.
Check all centralized exchanges, they do have an insider no matter what but we don't have all this details until you see a SEC clamp on them with law suit that's when they get exposed about insider trading. Even Binance that is known for putting the community first before their employees were once charge with insider infor trading and this lead to mass sacking of some of their staffs, there is always an insider information everywhere.
On top of that, literally nobody has to buy beforehand or at the release at the exact time or anything like that. Why? Because the token was sold, meaning that you didn't traded it to get it at first, you literally bought it from them to get it, after you got it, you can trade it, but all these tokens that you see? They were bought from Trump, then it hit the exchanges.
This is why there is literally no reason for Trump or his family to buy beforehand or anything, they already made so much money from just selling it as well. Hundreds of millions of dollars right in their pocket, so there is really no reason why they would be worried about this at all, we could make sure that they got away with it, by electing him president, so no amount of criminal thing he may do, he will go free, even though we are not so sure if this is criminal or not.
