It seems to me that listing shitcoins has been having the opposite effect over time. It's only going to accelerate as shitcoiners reform and go #Bitcoin only.
I was a shitcoiner for about 3 months before figuring out that Bitcoin was the way (although, I didn't fully grasp it and still don't years later).
People will slowly figure it out as they get rekt and Bitcoiners keep winning.
