As bitcoiners, we have found ourselves in situations where we needed money for investments or personal use. However, we never felt comfortable handing over our bitcoin collateral to a centralized lender. That is why we launched Firefish - a bitcoin-backed lending platform based on decentralization, and ease of use.
