otherwise if you can just PLEASE tell me where I can exchange (which website)
There are a couple of GOLD coins listed at
coinmarketcap, but neither of them seems to be your GOLD.
The only advice I can give you is to ask the guys from your coin/website. There's contact form at the end of the page.
Edit: Almost certainly nobody will lend you money with this collateral, so you better move the thread to Altcoin discussions.
