I don't think so. This is because the gold rank is a temporary rank. You don't get it forever.
I can try explain it like this.
If you were to get Gold (3 months). Then, after 2 months has passed, you upgrade to diamond. If there purchase from gold to diamond was at $50 then you had got those 2 months of Gold for free.
Hard to explain, but no.
TL? - No, it is not a permanent rank.
