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.
That is right, hodl only applies to those established coins in the market and not the ones that are newly listed in exchanges. What other people think is hodl can give them good results without even looking at the roadmap and just wishing for the price to go high. It's not an instant profit, but we also need to use our brain on how to deal with the market.
