If Mind on Air prevents revealing hands, can Exchange still resolve?!
Mind on Air is face-up and Exchange is activated.
No. Exchange cannot resolve because the required hand reveal cannot happen, and the effect is all-or-nothing.

●Mind on Air’s effect is continuous, so if you Summon Mind on Air and your opponent responds with Trap Hole, your opponent must show their hand until Mind on Air is no longer on the field (after Trap Hole resolves).
●If Mind on Air is causing your opponent’s hand to be revealed, and an effect that randomly selects a card is activated (like Robbin’ Goblin), your opponent shuffles their hand and you must choose randomly without seeing the fronts of the cards.
