The participants of this forum who join the signature campaign to promote a certain ICO project do not invest their money and this project, and therefore they can not be suspected of money laundering or other similar illegal actions. Therefore, it makes no sense to require from them data identifying their identity and especially copies of the relevant documents. Especially it looks strange in the sense that people are on this forum only under pseudonyms and have the right to confidentiality.
I see that members of the ICO team are using this opportunity with purely fraudulent goals. The requirement to provide additional data appears for some reason, not before joining the campaign, when each member of the forum can refuse such accession, and after the completion of the ICO, when the agreed work is already completed and the signatory campaign participants expect to pay the earned tokens. In this case, there is no choice for a signatory campaign participant who does not want to publish his data and provide copies of identity documents. They will in case of disagreement have to just abandon the earned tokens and this is what some companies are counting on. In this case, tokens are already counted and if someone does not claim them, they are simply assigned.

I personally stay away from these. Do your own research is the best way.

Sounds interesting. Can you please link the legit CPChain site and ICO breakdown\results please?

Hola fognoir, tu pregunta es la típica que nos hacemos todos cuando decidimos invertir... ya sea en criptomonedas, bolsa, forex, etc. Es bastante complicado responderla porque realmente no tiene una respuesta clara. Yo fui a un curso de inversiones en bolsa en Barcelona y lo primero que nos dijo el ponente fue: "Debéis destinar a las inversiones el dinero que os podáis permitir perder".
