My tradition is to hold, but the markets are getting more action, there are opportunities for making great gains intraday. I have been using whaletrade and poloniex for speculation purposes only by moving the coins in and out of a hardware wallet as needed. Only keep enough on an exchange to make your exchange. Then move it back to safe storage. You can protect yourself from a failure since I have been witness to 4 exchanges going belly up. The latest is btce who one day had my money and the next an FBI warning they were shut down.
