The $25-amount for OpenPoll is the registration fee to use your platform?
But nowadays, there are bunch of online survey sites that you can register for free and at the same time earning also.
But you have additional feature here, which is mining.

Also, 35% allotment for the team - development, marketing and others is a big percentage.
Aside from the fact that you are planning to sell 50% of your tokens.
That's too much already I can say. Roughly, 70-85% will go to the team. 
Please I need a valid and substantial explanation on this.
