I have a one portfolio for short term and one portfolio for long term investings. In short term potfolio i buy some altcoin and sell them again in a very short time range but in long term portfolio i buy most of the altcoins and wait for earn good profit from them.
Some tokens are perfect for day trade and short term holding. Some others are good for long term investment. This is why you need to differ them and make two different portfolio for yourself.
