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.
You cannot dictate others here to sell their holdings, let us respect their belief in the token on which they are believing for. It's because the market was down at the present time we have now its a sign to sell the coins, of course not! And after all its their money like what you said either. Instead of selling it much better and good to buy where we could have a chance to have profit in the future.
