For sure daytrading could offer tou more profit, if you got a fantastic skill, but it's too stressful to become a day trader because there are tons of work to become day trader, you must focus and search for a lot information to trade the coin and you will spend more time to keep on watching the screen to see the chart, long term investment is more enjoyable situation for me
I am not recommending it especially when you are working since you cannot watch the trend of the coins you are investing at from time to time, so make trading at least short trading just like weekly or monthly buy not daily, the transaction cost and the time that yo'll wait will cause you a trouble.
