Every single day there are different coins are introduced and new shit coin are produced. Don't get carried with your thoughts, Try to understand and be responsible of our action too, there are lot of people around the world who are taking advantage and make a use of it. The market right now is such a pain but also a learning to everybody. If you cant carry it anymore then leave nothing but footprints.
You have it they are shit coins and there's no way to take advantage of those coins if no one is ever trading with them.
If there are traders who are still choosing those coins, it has a small impact or it really don't have if they are very few that makes the volume almost nothing.
For a newbie that keeps on complaining about the market's volatility, it's okay to tell this but for someone who's complaining on how many shitcoins are there, I think that's normal.
