New way to confirm diamonds

Hi friends recently i lost 300 diamonds and wen i complained about that to supercell they told me that you hav misclick speeding up button. I was really frustrated, i cant even find where did i speed up. So i came up with a simple idea to prevent loosing diamonds.

When we touch the speeding up button we should get a dialogue box asking are you sure below that yes and no should appear. By this way we can avoid loosing our diamonds.

Supercell should get it in the next update....
