Normally both the long-term and Short term investments are preferable, it just depends on what the investor needs, let's be realistic; short-term investment can fetch you money atleast monthly or weekly as the case may be though it has little profits but atleast one can still hold on to it as a means of daily survival if you do not have any other side hustle, while Longtime investments has every possibility of making you a Millionaire so while investing in it means you should have make up your mind to HODL no matter how threatening the market could Seem so my point is, both of them are important and serves different purpose too.
