the team involved in this project is great, now the project has reached its softcap, just develop its future hopefully later hardcap it will also be achieved with maximum.success for this project.

I'm so stupid when attending crypto currency, who can help me to get money back? I also ask many traders who has experiences in this one, but I still lost money

Should I hodl Ether or sell and invest in something else ? And if yes, then what should that new thing be ?

All good points. I agree with the fact that we cannot entirely blame a campaign manager if a project turned out to be a scam because some ICO's are actually investing to have a well-written whitepaper just so they can entice the community and make their project looks legit.

I, on the other hand, check their websites, first hand. Because their website, for me, is the entire compilation of what their project has already gone through so far. Their website must have their whitepaper, their team members, the road map (this is very important since this will give us a vision of what they have already accomplished and what they aims to accomplish in the near future.) Also, all about the details about their ICO and token sale should be included, well written, links are all working and such. A good ICO enters in a complete, well-made and a well prepared website and all its aspects and parts.
