I know he is into FOMO because he seems so aggressive and like to get instant return.
He told me that since I'm a veteran, he would like to ask some advise on what coins will pump in the coming days so he can invest on it.
What do you think should I do guys? how can I help him?
The first mistake you made is telling him that you are making such an investment at all, and the second will be if you really give him advice on which coin to invest in - in case he loses money, he will blame you first and then everything else. If he wants to get rich instantly, then advise him to go play the lottery or sports betting, because with the attitude that your friend has, there is a good chance that sooner or later he will lose everything he invests.
When it comes to someone's money, then you should draw the line and not get involved in such things - because of money, best friends become the worst enemies, and they raise their hand against each other.
