First there is an announcement, then there is 3 year Roadmap,
extended each year with meaningless additions, fake recruiting of
employees, trade interrupts, software announcements, wallet updates, changes
quizes, games, givaways, airdrops, forks, ICOs etc, etc, etc.
Unfortunately some countries banned ICOs so these "fake projects" can't scam people out of their hard-earned fiat. On an additional note, some replies also mentioned use IEOs. However some of the same countries are also going to ban or have already banned them.
You may want to research tokens or STOs (secure token offerings) that are tied to legitimate startup projects. Those may be of more interest to you. I also thought that all virtual coins and their projects were a scam until recently. Then I started researching STOs with real-world business applications and attending a few AMA sessions headlined by these startups. Those really informed me that some projects are really trying to solve challenges in business, medicine, the arts, etc.
