Day trading on cryptos seems a little bit more difficult to me than day trading currencies - on Forex, you can literally one-click buy/sell, whereas on the crypto exchanges you have to manually type in your prices/amounts? So if you needed those split-second reactions, it's not exactly going to work in your favour all the time, and the price must slip a bit too depending on how large the exchange is and the volume going through it.

Do any of you use a particular exchange for day-trading verses long-term? Long term I thought the best practice was to store coins in wallets off exchanges too?
