Apparently adding salt to eggs can cause them to “go gray” and become watery (via Huffington Post). According to Gritzer, the longer the egg was exposed to salt, the more time it had to coagulate, so in theory the egg exposed to salt for the longest period of time should be the toughest.

Despite folk wisdom, salting your scrambled eggs before cooking them will result in more tender eggs, as salt dissolves proteins and allows them to create a moisture-binding network. Beat your eggs with salt 15 minutes before cooking for the best results.

Egg white solidifies more quickly in hot, salty water than it does in fresh. So a little salt in your water can minimize the mess if your egg springs a leak while cooking. The egg white solidifies when it hits the salt water, sealing up the crack so that the egg doesn’t shoot out a streamer of white.

Salt neutralizes the negative charges in the protein molecules and allows the proteins to bond (coagulate) at a lower temperature. The faster bonding also results in a weaker bond so the eggs end up being more tender and moist if you don’t cook them too hot.

If you are in the habit of adding milk or cream while whisking eggs, you can stop. Now. Milk won’t make eggs creamier, fluffier, or stretch the dish out. What the milk really does is dilute the flavor of the eggs, making them rubbery, colorless, and something similar to what you would find at a school cafeteria.

Remove your eggs from the stovetop before they’re finished cooking. They should still look loose and a bit runny. (If you prefer eating custardy eggs rather than well-cooked ones, remove them when they look very loose, and the curds have just begun to set.)

The eggs should be moist—very moist, without a hint of the rubbery texture that overcooked eggs can get. But they shouldn’t be runny. You’re likelier to see this in the whites of the egg than the yolks.
