I'm the one who bought the domain from the seller. Been holding it since then as it's value appreciates.
Can you prove it? Well no, you can't.

Unfortunately for you, you won't get any loan offers with this kind of collateral here especially when it has a background story like yours...
Your best chance? Since
"it's value appreciates" resell it elsewhere and lock your thread.
