In 2017, I managed to get involved in an ICO, which later went bust. It's good that this was a trial experience for me, and I did not risk a large amount. Now I would never do this, but then I still believed in something.
I wanted to invest in an ICO in 2018, but I stopped. Although, I cannot vividly pinpoint what made me not to invest in it, despite having the fund at that time. TIll date the project has not listed on any exchange. The simple truth about it is that, it's a scam project, because they disappeared all of a sudden. Although there were very good ICOs, as at when it was still very much relevant. Things have now changed, so it's better not to invest in any ICO project.
