BitVc is a new trading platform which allows margin trading of Bitcoin and Litecoin. Like Huobi, there will be zero trading or withdrawal fees. BitVc is based on Huobi's API and will support BTC/LTC derivatives and financial instruments. BitVc will be focused on margin trading, derivatives, and other financial instruments, while Huobi will continue to be mainly a spot trading platform. The API will be opened later for other developers to create applications on it. BitVc was created by the people behind Huobi, which has an impeccable security and performance record. It is registered to Huobi's subsidiary company in Hong Kong.

BitVc features a new product/service called Yubibao, which is an interest-bearing BTC/LTC account within BitVc. You can move your BTC/LTC into your Yubibao and withdraw into your normal account instantly and at any time. Yubibao gives risk-averse people a safe, easy way to put their coins to work for profit. Interest is derived from traders who borrow to trade on margin. Rather than setting your own loan terms, BitVc pools all the deposits in Yubibao and offers the same market rate to all savers and borrowers.

BitVc is currently in invitation-only mode, but you can send me a message if you want an invitation code. Your feedback would be much appreciated.
