Not good choice if you do day trading because you will spend more fees than holding and waiting for the higher price before sell..
Also the benefits of holding coins is to get the maximum profit you can get.. if you bought them in low price ..
And honestly you can't monitor them in time to time.. If you are investing in bitcoin i suggest you to hold but there are some altcoins are sometimes the price is getting worst if you still holding them. So what should you do is to investigate if they had a solid devs that you think in the future that the price can increase higher.. there are lots of coins honestly are getting increase its value for long run ..
