We obtain an existence condition and a stability condition for static, spherically-symmetric black holes in asymptotically-flat spacetime by using scaling arguments. The formula is then applied to the scalar field model with an asymmetric parameter of the scalar potential. We numerically find the solutions of the equation of motion for black holes that are asymptotically flat and have a regular event horizon. We show that the black hole solutions satisfy the existence condition.
Also, we show that the possibility of having stable black holes under radial perturbations in the asymptotically-flat spacetime exists.
