Unity2D: Creating a wavy score text animation - unity3d

Question

I want to animate my score text into a wavy animation each time the player picks up a coin as well as make another wavy text animation but going the opposite way each time the player loses some coins. I already have a code (shown below) to make a certain text do a wavy animation, however to do this I assigned each character of the text to either go up or down to initially make a wavy animation, as shown here:
.
My problem is: If I were to do this method for the score text, there is no telling how much coins the player will get and so it will make it difficult for me to estimate how much characters I would need for the score text as the possibility of the player adding a new digit to the score is kind of random.
So is there a way for me to create a wavy text animation to my score text? Thank you!
public GameObject WaveTextObj, text1, text2, text3, text4;
// Use this for initialization
void Start () {
text1.SetActive (false);
text2.SetActive (false);
text3.SetActive (false);
text4.SetActive (false);
StartCoroutine (WaveEffect ());
}
IEnumerator WaveEffect() {
while (true) {
WaveTextObj.SetActive (true);
yield return new WaitForSeconds (0.3f);
text1.SetActive (true);
yield return new WaitForSeconds (0.08f);
text2.SetActive (true);
yield return new WaitForSeconds (0.17f);
text3.SetActive (true);
yield return new WaitForSeconds (0.19f);
text4.SetActive (true);
yield return new WaitForSeconds(0.4f);
WaveTextObj.SetActive (false);
}
}
NEW UPDATE
text = "Testing";
string[] characters = new string[text.Length];
for (int i = 0; i < text.Length; i++)
{
characters[i] = text[i].ToString();
}

Use Mathf.Sin(Time.time)
public GameObject WaveTextObj;
public GameObject textPrefab;
IEnumerator WaveEffect(string text) {
//clear out the existing text
while(WaveTextObj.transform.childCount > 0) {
Destroy(WaveTextObj.transform.GetChild(0));
}
//create new text
float scalar = 0.1f;
float timeScalar = 3;
for (int i = 0; i < text.Length; i++)
{
GameObject o = Instantiate(textPrefab, new Vector3(i * scalar,0,0), Quaternion.Identity, WaveTextObj.transform)
o.GetComponent<Text>().text = text[i].ToString();
}
//animate text
while (true) {
int i = 0;
foreach (Transform child in transform) {
Vector3 p = child.localPosition;
// By setting each text object's y position to a value controlled by a sine wave,
// they will jiggle up and down. Their index in the string handles each letter being
// at a different point on the wave.
p.y = Mathf.Sin((Time.time + i * scalar) * timeScalar) * scalar;
child.localPosition = p;
i++;
}
yield return new WaitForEndOfFrame();
}
}
Up to you to figure out how you want exit the loop. Several values are arbitrary.
