For me personally, x2 to the balance means that the plan has been completed 100% and there is no point in taking further risks. I have not had the goal of hitting the jackpot for a long time since I no longer believe in it, and I consider multiplying my initial balance a very good result and I can finish game. Discipline is my faithful friend.
That's actually a good mindset as there's no high assurance that we will continuously win in gambling.
