You might end up holding dead coins if the project gets abandoned
You might miss swaps and end up holding worthless tokens
Delisting of coin/token and you miss the withdraw period (in case you store coins/tokens on exchanges)

Take time to follow news/updates on the coins/tokens you invested to minimize the above listed risks. Checking up their telegram/discord/social media once or twice a month will help.

Perhaps you are misunderstanding a little about hold an investment for a long time. Long-term investment does not mean that you will not be interested in the project, long-term investment is to give information that makes yourself believe that it is a project that will thrive in a few years.
