Kraken has margin trading, which allows you to hold negative positions in BTC. However, this means you are borrowing the BTC that you're selling, and the interest on that is rather high (0.01% per 4 hours). You also need to keep EUR or USD as collateral in the account to cover potential losses when the price goes up.
