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?
Unfortunately, the prices of many coins that are in my portfolio have fallen very much. It makes no sense to sell them today. Some of them may grow in price in the future, but I doubt it very much .. The crypto market is unpredictable. And it is very frightening and annoying ...
