Make a gameobject stick to the very bottom of the visible camera area

Unity Engine

I’m not sure if I do this correctly but I want to place my player always at the very bottom of the screen. Regardless of screen size, aspect or whatever. The problem is, I scale my player depending on the screen width which than leads to invalid values for the Y position. But how do I calculate the proper position?

This is what I currently use to scale my game objects:

public class Scaler : MonoBehaviour
{
    void Awake()
    {
        var screenWidth = Camera.main.ScreenToWorldPoint(new Vector3(Screen.safeArea.width, Screen.height, 0)).x;
        var spriteRenderer = GetComponent<SpriteRenderer>();

        if (spriteRenderer == null)
            spriteRenderer = GetComponentsInChildren<SpriteRenderer>().OrderByDescending(r => r.bounds.max.x).First();

        if (gameObject.tag == "Player")
        {
            var playerSize = screenWidth / 5f;
            var scaleFactor = playerSize / spriteRenderer.bounds.max.x;

            transform.localScale = new Vector3(scaleFactor, scaleFactor, 1);
        }
        else
        {
            var playerSize = screenWidth / 20f;
            var scaleFactor = playerSize / spriteRenderer.bounds.max.x;

            transform.localScale = new Vector3(scaleFactor, scaleFactor, 1);
        }
    }
}

And this is my current state for the placement (which always leads to a way too low position for the player):

public class PlayerPlacement : MonoBehaviour
{
    void Start()
    {
        var orthographicHeight = Camera.main.orthographicSize * Camera.main.aspect;
        transform.position = new Vector3(transform.localPosition.x, -orthographicHeight, 0);
    }
}

Is there something I miss? Or is there a better way for proper scaling and placements of gameobjects?

maybe move center (sprite pivot or make it child) of the player at the bottom
and you can try with:
