The price is not a big concern, as a collateral you can use 1/10 of its value if that is the largest retracement of exchange rate during the latest 4 years, actually given a standard deviation based model, you might be able to use 1/4 of its value as collateral

And if it can work as a collateral, it could also be bought with a loan, that will ignite a rally which could be magnitudes higher than those rallies we have seen so far
