I think Long-term would be a good idea, you will learn a lot from a bigger perspective which ultimately helps you generate profits on a consistant basis. In the long-term, you can control your emotions which is really important thing to do in crypto market. So, my suggestion is to go for Long-term.
no one knows if is really good o hold a coin for long term since we are not sure what will happen to crypto in the next more years. in day trade you can earn daily basis even in short trade you have a chance to multiply your capital.
