Started a speculative attack on fiat last week by borrowing fiat using my bitcoin as collateral on
@Firefish - both a 18 months and a 24 months loan at around 9 and 10% yearly interest (including fees).
Process was super smooth. Firefish did a great job making it simple and easy to follow. Fiat was in my account within hours after the collateral was confirmed (3 blocks). On a Saturday!
Exciting!
