There is potentially an infinite spread when the market is no bid to $0.0001 offer. The market makers must first bring down the stock to this price to participate in cellar boxing. The lower they can drive the share price, the wider the percentage spreads they can exploit.
Once a microcap stock is boxed in the cellar, it doesn't have many alternatives to rise higher. An obvious alternative is to reverse split the stock, but historically, these splits have been ineffective—the market cap generally gets hammered and the stock reverts to its pre-split price. Another approach is to coordinate a prolonged purchasing attempt and force the stock "out of the cellar," but in most cases, a naked short-sell order will appear out of nowhere to meet each purchase order.

The shareholder base can sometimes generate enough purchasing pressure to keep the market at a $0.0001 bid and $0.0002 offer for a limited time. After that, the market makers repeatedly strike with force by selling to wipe out all of the bids. When retail shareholders watch this happen a few times, they tend to sell their stock the next time a $0.0001 bid arises. The $0.0001 bid and $0.0003 offer market leads to a stalemate, where market makers may enjoy significant spreads while the real shares are sold at very low price.
