EdgeCollider2D doesn't move with Transform

I am drawing lines using a linerenderer between prefabs and my player. I want these lines to have colliders so I decided to add a EdgeCollider2D to the LineRenderer. The initial collider gets drawn right but as soon as I move the player the starting-point of the collider stays the same and doesn't follow the player.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class CoinShooting : MonoBehaviour {
     public Transform firePoint;
     public Transform player;
     public GameObject coinPrefab;
     public float lineWidth = 0.03f;
 
     private List<GameObject> coins = new List<GameObject>();
     private List<GameObject> lines = new List<GameObject>();
 
     void Update() {
         if (Input.GetKeyDown(KeyCode.Mouse0)) {
             Shoot();
         }
     }
 
     void FixedUpdate() {
         int index = 0;
         foreach (GameObject coin in coins) {
             LineRenderer lr = lines[index].GetComponent<LineRenderer>();
 
             lr.SetPosition(0, coin.transform.position);
             lr.SetPosition(1, firePoint.position);
 
             Vector2[] points = { 
 new Vector2(firePoint.position.x - player.position.x,
                         firePoint.position.y - player.position.y),
 new Vector2(coin.transform.position.x - player.position.x,   
                         coin.transform.position.y - player.position.y) };
 
             EdgeCollider2D collider = lines[index].GetComponent<EdgeCollider2D>();
             collider.points = points;
 
             index++;
         }
     }
 
     void Shoot() {
         GameObject coin = Instantiate(coinPrefab, firePoint.position, firePoint.rotation);
         CreateLineAndCollider(coin);
     }
 
     private void CreateLineAndCollider(GameObject coin) {
         coins.Add(coin);
 
         GameObject myLine = new GameObject();
         myLine.transform.position = coin.transform.position;
         
         LineRenderer lr = myLine.AddComponent<LineRenderer>();
         lr.startWidth = lineWidth;
         lr.endWidth = lineWidth;
         lr.startColor = Color.blue;
         lr.endColor = Color.blue;
         lr.SetPosition(0, coin.transform.position);
         lr.SetPosition(1, firePoint.position);
 
         Vector2[] points = {
  new Vector2(firePoint.position.x - player.position.x, 
                          firePoint.position.y - player.position.y),
 new Vector2(coin.transform.position.x - player.position.x,     
                        coin.transform.position.y - player.position.y) };
 
         EdgeCollider2D collider = myLine.AddComponent<EdgeCollider2D>();
         collider.isTrigger = true;
         collider.points = points;
 
         lines.Add(myLine);
     }
 }

The collider gets drawn just fine. alt text
