Looks like a few sellers in around that 50 cent range.....To keep the market maker from selling the bids have to be built up along the way.... ..First in the twenties to see what comes out,
then in the thirties to see what comes out,
then in the forties to see what comes out...ect. all the way up.
Right now the MM only sees 1 bid at 20 cents so he's happy to sell or short you stock at 49 cents. All in my opinion only
