I've read the thread and Cuban's AMA. His advice at the time was to hold if you can afford to. I don't know if that advice still applies considering everything that has went down since that interview. Robinhood and other brokerages stopped trading of GME that stopped the momentum and many rumors that market makers and hedge funds have been manipulating the stock to get the price down allowing them to cover their shorts at a lower price.
Plus, not sure how much stock I'd place into Reddit at this point. Many on there have seen very large losses and are more emotional...all 'Diamond Hands' and stuff. I'm willing to take the loss, but if there is any fundamental reason remaining that drove the original GME spike I'm willing to wait it out.
