A shit coin can be identified by any of these characteristics:
1. No tangible product(s)
2. No development team
3. Too good to be true claims (exaggerated claims)
4. Selling point of the token is the price it will hit an exchange with (price discussion prior to listing)
5. No technical plans
I have a question about your second point, how can a coin go through ICO without a development team? Just curious as to how one or a few persons can handle that.
Maybe he was talking about the ico that has no team member but as long as the developer is really proffesional even a single person can create such a new system just like byteball which has created DAG system and this has already copied by NANO and IOTA. I suggest you to see Byteball and it's created by only one person.
