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.
The idea of hodling for me is only applicable for bitcoin and eth only, if you have alts on your wallet it is better to convert it to btc or eth and hold because it will work for a shorter time rather than wait for the coin price to recover after the ICO.
