- 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.
You are correct with your observations. All the three results of hodling long-term you mentioned I all have experienced giving me a great loss in my assets. So that is why I am now a bit picky and only follow a few of the top coins so as to have control and fully manage my assets.
