Thanks for reminding me of what I already know. I will be exposing the projects you bump as a scam. To be fair to each project, they have nothing to fear if they aren't a scam, but I'm pretty certain more than half of them are.
How do you define a scam project or not? What are the criteria? For example, the famous and popular worldwide project Dash. For several years they have been making their payment network. Made? No, they did not ... Masternode Dash cost over $ 1.5 million in December 2017 - today it costs $ 90 thousand ... Dash scam? No, no and no!
Then why other projects with masternodes and unfulfilled plans and promises you refer to the scam? I think that this is not the right judgment. Only time will judge what teams are scam and that are not.
And sometimes it can not be decided whether a project is a scam or not, since some might just fail because the team is bad, but that doesn't make them a scam.
