- 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.
of course, if you are holding a huge amount of tokens, you should follow it's development, the price, the platform and are they following everything that is in their roadmap and whitepaper, and the worst thing that can happen to you is when you have a huge amount and you found out late that it's been delisted on exchanges where you have the chance to sell it.
