Currently on the coinmarketcap site only about 1590 projects compared to at times more than 1700 projects. They have left many projects without developers or scam projects. I personally invested in some of these projects and lost a lot of money like bitconect and centra. Do you trust the projects you are investing in and will keep them for a long time until they succeed or are they just looking for profit in the short term?
Not all projects are fraudulent, and fraudulent projects started in 2017. Before this, the environment of the entire market was still relatively good. However, I believe that there will be new solutions after this year.
