While I'd love to loan you 3BTC, the risk is that Ripple could (and possibly will) completely crash in price. The domains are nice but it's nowhere near 300$.
Do you already know my domains?
No, but I doubt a domain can be worth 300$. (I could be very, very wrong here.)
Domains could worth even millions. Domains are priced based on pr, age, traffic, domains length, exact word match. Try visiting sedo.com or flippa.com.
Are your domains worth around 300$? If so I'd take this loan.

Wow.
