The number of good projects is decreasing since 2017. I remember in 2017 there was a lot of promising projects, and you had the possibility to earn good profit by investing in any ICO project almost. Now the situation is harder, and you need to make a careful and long research before investing your money or time in any ICO project.
Making a good profit from a certain project does not explain that the project is a good one, there are so many projects that gave us a huge profit. Even Bitconnect itself, the most well known HYIP or Pyramid Scheme project gave us a huge profit daily.
