Feel free to comment your ideas and opinions.
short term is more advisable for experienced trader as they have enough knowledge on chart and other trading signals but if you are a newbie trader and don't have enough time to monitor market condition daily better to stick in long term investment less stress and you don't need to check your account daily.
