It is easier for you to trade all day may be because you are not busy but for someone that is very busy, that may not be possible considering his or her schedule for the day. Investing in a long term and a short term is a choice of whoever that want to invest, some prefer to invest in a long term why some others on a short term.
long-term investment or short-term investment for me are all the same, the difference is financial management.
