Day trading is the most difficult form of trading and honestly I dont consider even long term one as some easy job. Predicting the upcoming dip or surge itself gives a tough time.
If you deal with the day trading, you will risk much. Now, the market is not stable, and you will never guess the price of the altcoins. I suppose that the long-term trading will give you more benefits.
Day trading is a good way to have a source of income, it really helps those traders to gain more if they are doing day trading, yes for those experts of already have their strategies they can really have a quick profit by doing day trading.
I think this depends on you. You can make good money from bitcoin in trading in either case of long term and short term. But mainly, people are easy with long term trading that is often associated with holding. Reason is, you may have time to increase the value of your money. But for that thing you need to work out hard as well. Day trading doesnt make your bigger money earner.
