Player stops moving after input.getkey is false

Hello!
I am making this 2D space exploration game, and I want my player to not be stopped the instance the person takes their finger off ‘W’. I would like the object to keep moving at exactly the same speed when the person takes their finger off that key.

Would appreciate any help! Thank you!

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour {

public float rotationSpeed = 100f;
public float movementSpeed = 1f;

// Use this for initialization
void Start () {
	
}

// Update is called once per frame
void Update () {
    if (Input.GetKey(KeyCode.A)) {
        transform.Rotate(Vector3.forward * Time.deltaTime * rotationSpeed);
    }
    else if (Input.GetKey(KeyCode.D)) {
        transform.Rotate(Vector3.back * Time.deltaTime * rotationSpeed);
    }
    if (Input.GetKey(KeyCode.W)) {           
        transform.position += transform.up * Time.deltaTime * movementSpeed;
        movementSpeed += 0.1f;
        
    }
}

}

if (Input.GetKey(KeyCode.W)) {
transform.position += transform.up * Time.deltaTime * movementSpeed;
movementSpeed += 0.1f;

 }

Change to =

if (Input.GetKey(KeyCode.W)) {           
     movementSpeed += 0.1f;
 }

transform.position += transform.up * Time.deltaTime * movementSpeed;
