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.
ICO investment has decreased in quality, selling all the coins that are decreasing for ICO investment is a bad choice, first we will only get substantial losses and secondly, even though you read the roadmap and know that the developer then invests in ICO it is very difficult to recover our losses which from the beginning we experienced. Now there is no guarantee of profit if we invest in ICO, indeed there is the best among the best ICOs, but are our profits for invesment is large too? in my opinion the profits of ICO investment are very small in this year.
