Do you realize cash retail can't short short a sub penny? Most brokers don't allow it. Robinhood don't count because they're going down anyways.
Reality is ALL brokers will charge outrageous fees per share like 2+ dollars a share, PLUS you will be required to have a large deposit in the account if not required to be a margin account.
No sane broker is going to tie up a million dollars to make 1K total profit if they're lucky.
