Prices assume you place offers and wait for them to fill. Insta-buying and insta-selling pays the spread twice.
Selling below the breakeven price loses money, even if it is above what you paid.
4h volume is 7 items (2/hr, average over the last 24 hours). Too few trades, or too little bankroll, to expect a fill. Sized to a 10m bankroll; set yours on the home page.
