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.
