The secret to a perfect crispy fried egg is a hot greased pan. Don't drop in an egg until you are sure it's hot enough. Then crack in the egg, with your face away from the pan. When the egg hits the pan, it'll make a funny noise, the egg white bubbles will burst and splatter over the pan and the edges will immediately start to turn into a perfect crust. Let the egg cook until the whites go from translucent to completely white and aren't runny anymore. You can brush the uncooked whites over the cooked parts with your spatula to ensure the whole egg white is cooked through and through.
