The human characteristic never be changed easily, although they have felt how the FOMO can make they lose a lot of money they will always do it. Because they have a hope that bull market now is reallt different with the previois bull market. There will always be a defense from them to do everything they have done. You don't have the right to forbid them, I think there's been a lot of education about how FOMO effects however they can interpret for themselves what FOMO means.
