Yes, that is as expected. In 3 months, those 80% of the supply that you mentioned will be unlocked to Trump and his team at which they would have the opportunity to dump on the market and extract as much value as possible. If we are being honest with ourselves, a president has no business launching a memecoin. Otherwise we'll have all countries and their president launching memecoins too.
If Trump and his team believe in the TRUMP token, they'll unlock it in 3 years instead of 3 months and maintain their vested interest to see it succeed.
Imagine every president doing this stuff on SOL, jesus

Surreal to think about it, even considering that Trump alone for now holds the spot in this type of thing.
