Right, that is why we discuss about people who not want to research by themself and only follow someone that influence him in crypto. Because he will always follow what other said and can't decide by themself.
as long as they benefit and can control their own investments I think that is not a problem. because the problem is when he loses investment and he can only blame the person and not accepting the loss he received is his fault.
yes, because not being careful to invest causes him to lose money. blame others for the mistakes he made from the beginning. eradicating fraudsters in the ICO is very difficult because they usually use other people's identities.
About anonym team of developer, i think it is our job to warn others. In here i found people give an suggestion each other if the project not really good in general. Like if no escrow, anonym team, etc. Maybe what be blamed in this discussion is someone who told them(investors) to buy coin with it's hype.
