Yea the volatility of the altcoin maybe is the key factor for trading but there are still 3 important questions we can ask for the trade.
1- Which altcoins do you prefer for your daily or short time trade generally?
2- And why do you prefer?
3- Do you have any daily income goal or you trade as much as you can with this altcoins?
IMO best coin for day trade are:
Litecoin and Etherum - high volume and pretty big stability
allso using them you can use laverage in some places for trading.
For day trade, Litecoin and Ethereum are not fit for this since they are in the status of their resistance level. Day trades are meant for those who have at least 20-30% in their volumes in daily basis. But Im not saying they can't be considered. It's just that you will spend many hours monitoring the price for that mentioned cryptos just to make a profit doing day trade.
Feedbacks are welcome to my statement.
