On a platform called ICO Tracker there is a "role" of curator, who rates ICO's and must invest in the one he's rating. In Dolphin BI, when rating anything, users don't have to invest in it, do they? And I don't undertand one small detail. In Dolpnih BI do users rate widgets or ICOs?
Well, the Expert can rate an ICO negatively - it is not really logical to ask them to invest then, is it?

We do not make our experts invest into anything (it is their own business whether they do that or not), because otherwise they wouldn't be really objective or impartial.
