Can you guys help me?

I bought the currency and it had a 2,500% appreciation.

Then it went up to 2,890%, in this case it appreciated 390%, right?

I thought that in this case my capital appreciated 390%, but that wasn't the case, it only went up a few dollars. Can someone help me with how it works??
