that's the main problem.
unfortunately there was some fake ICO.
these projects as well as all others now have a hard time to survive.
I think that the icos will not bear their fruit until a few years later.
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?
