For me most of the coins will fail in the most obvious question: What problem do your coin will solve?
I read a lot of threads and whitepapers but it's a shame, they don't have a simple explanation why we have to believe in the project, how people are going to use it and the rest is only words, just to gain some money...
the 3 type of scams i explained you
1. stable coins
2. huge supply projects with billions of coins
me and few other have around 100k bots ** which spread this info to save other people who their logic is work , if the logic function is broke they live in a dream that xrp will hit soon 30 usd and other things stable coins is great while its stable smart scam
