I'm not spreading FUD and everyone is free to do whatever he wants. After all, it's your money.
What I'm suggesting here is to take all the tokens and coins you're holding and start reading the whitepaper, check the roadmap, see the team behind that project and how active the developers are is by looking at the GitHub repository. If it's not looking that good, don't think twice, just go and sell regardless of initial buy price because you'll be cutting your losses this way.
I understand that saying "hodl" is nice etc but you should use your brain and don't be blinded by the idea that every useless out there will go to the moon. Only a few are worth investing in so instead of holding random coins, you may want to target something that has been here for a long time and still doing well such as ETH, BTC.
Sounds like good advice! But in practice, it is impossible to sell on time and the price falls within 5-10 minutes after the listing, while you send tokens to the exchange. And nobody wants to sell for a penny, so you have to be a holder.
