If you don't have that time to assess and just quickly jump into any project to participate, there's no one to blame,
it's so happened that this market have both good and bad it's participants decision to join or forget about it. Your
action needs to properly assess everything before you ride with the project.
I have a different mindset than you, if I don't have time to evaluate something, I won't waste any more of my time on such things. In general, it is absurd to unintentionally work for projects with fraudulent purposes and ask them to pay, it is clear that we find such projects very risky, but not without effort spent will be duly rewarded.
Why is it a big risk? First of all you don’t need to make investments. You just plug a product by doing different tasks like following social media, make up a video about the project or type an article about it, and then you might be paid for it.
Secondly, I strongly believe that if you do a research you will avoid scam projects. You always should go through social media, web-sites and overview the team members.
