You need to invest very carefully and very carefully when choosing a project in which you invest. I choose very carefully and recently found the project Gexan, which will conduct the IEO. I recommend you to get acquainted with this project. These guys are very cool. Gexan has an existing product - a valid lottery.
I have seen the GEXAN project and indeed it is good to invest, but there are several other projects that want to do an IEO that is no less good than the gexan project too, so in this case it needs to be looked at which is better to make investments in the IEO.
if you believe in the Gexan project, my advice is that you better invest in it but don't need too much so you still have the opportunity to invest in other projects.
in my opinion this is the best way to do it now because I can't trust 1 project now.
