what is the place with most liquidity to sell short bitcoins?

[ANTOSOR]

Hello, I've been looking for a long time on the net sites to sell short BTC's ( like the ICBIT), but most of them barely have enough liquidity. I would like to know if are there any other markets or sites where I can find more liquidity to sell in short BTC's. Million thanks. Best regards

probably too early to be shorting it, its a strong bull market
