That's 4 out of 15 questions (27%) that had either incorrect, or misleading answers. I suggest you learn a bit more about bitcoin, and make more of an effort to put correct answers into your quiz to avoid confusing people who assume that one of the options must be correct for each question.
First of all, thanks for your reply and for the attention you pay to our project. I appreciate that.
I have to say that we've spend a lot of time on this project and we asked lots of people for advise. So if you can provide us some information to approve your words - then do it. Otherwise all your words didn't make any sense.
And secondly, even the simplest questions might be imperfect. Everyone have their own opinion about Bitcoin and every topic related to it. This is a problem that we met with. So that is the reason why we ask you to take this quiz easy and be more patient.
