5. PlaygameNote: i wanna to share some list by scam projects, poor ProjectS so you can analyse right now. Actually there was many scamming projects like (2018-2019) years, so i have share some list of my mind.Your list is accurate about Emirex, Btwings, Pure Gold etc. We can also add DACX to the list. I believe these projects are close to launching their products but still their devs look they are sleeping. We hope that someday they wake from slumber to continue what they have started.
