What's there to be cautious about? Crypto space is opened for new ideas and they are welcome at any time, we only need to figure out which project team are serious about what they introduced, ICO, IEO, DEFI all have high quality projects backing them up so new ideas are highly welcome.
The projects itself is not what we need to worry about but the ones who are pretending to be projects but in the truth is just scams. That is what the OP is trying to explain here where new projects coming out left and right it will be harder for new investors to see what is real and what are the scams ones that is why we want them to be aware of what they are trying to do to lessen people getting victimized by it.
