Thanks for giving this reference OP. It's a great thing to ponder about and it just shows how much a lot of people have rode the hype and probably made a plan to create something that hopefully would stick. It's just that all around the world, the ones that would stay are the ones who have a lot of backing and maybe the most unique way. I do hope that there will be a way to determine what cryptocurrency will stay.
It's important to note as well that a coin could have failed but it might not be a scam it is still important to be vigilant
TBH, I thought that the percentage might be higher, but that's still a lot. Not every coin that died is a scam, that's for sure, but in the end, it doesn't really matter.
I think at the rate that we are seeing or the number of negative outcomes of different cryptocurrency projects that surround us, here in the forum, it's likely become anchored to that because of the part where we see so much here that didn't work versus that worked. It can be higher too with all the negativity and possible scams that are happening around us.
