Here you are absolutely right, the approximate ratio of the scam is 60% to 40%, it is very difficult to see the project when everything is really very carefully compiled and executed, for example, I try not to go into long-term projects that last more than 1 month. Recently I took part in one project, it lasted in two stages and for a very long time, as a result, the time was spent and the project scammed, during this time spent there were a bunch of projects where it was already possible to make a profit.
