Well, I know of Multiversum.  It is a huge crypto project that attracted the attention of many investors back then in 2018/2019.  I did a lot of hard work before I could get little amount of that token hoping that I'm in money already when it is listed on exchange.  Unfortunately, the team was misled or given wrong advice.  The project failed to reach exchange eventually and it has became a decorative coin in my wallet now.
