Tips:
Researched projects in which you want to invest (DYOR - do your own research) and do not trust anyone blindly, no matter who in your environment is just totally convinced of a project.
Have no unrealistic profit expectations, no one gives you money
If you do not understand a system or project, do not invest in this project.
Some people are already aware on this kind of thing but they do still decide to continue on what they are doing just for the sake of earning easy returns on a short possible of time. Recognizing them isnt really too hard and even just with a simple logic and common sense we can really able to identify out. I dont know why some people do make theirselves of their own greed and they do cry out later when they are scammed. Bitcoinnect shit scam is one of the examples, even just seeing it on very first time it is already a scam to me.
People need to be accountable for their own action and they should put in their minds that research is key of everything but there are so many people are so lazy upon doing it that's why we see so many people cried for their own foolishness, and I agree with hard to detect if the project is scam but their is certain indicator that will slowly shown and it will indicate us to exit before we get slap badly by their faster exit.
