There are various kind of old crypto projects that has no team but still they are among the best projects today, I believe this happened because many old projects followed the footstep of Bitcoin, bitcoin would have been in tougher situations if the team or ceo is public I believe but today it's a complete different story or should I say experience? Since the birth of ICO we've seen tons of scam projects that aren't scared of revealing their faces even when they knew they are going to exit scam on investors fund, so for me hidden team members or not still doesn't make a difference..
Why would anyone want to invest in a project with hidden teams?
It just does not make you a wise or vigilant investor if you do so.
I see this startegy as high risk and it is just like throwing away your money or you just do not care about it.
