They cannot allow the traders to keep trading on margin when they have lost so much monies already. Those monies will be eaten by Robinhood because those small traders do not have monies to cover their huge losses. At some point, Robinhood will probably, go after those traders to pay up. Small traders pain is just starting. This is a very expensive lesson for them.
What small traders are feeling pain? Or do you mean after the eventual/inevitable dump?
