Define Magic Mouse . I have never heard this one before that Satoshi mentioned this thing before because he is hiding his identity for his own personal reason, and then you are going to say that he is selling a Bitcoin Magic Mouse to raise $200,000 Dollars to donate to a charity? this is ridiculous, because he wouldn't reveal himself just for this thing because he can donate a $200,000 or whatever amount of money he wants to donate to a charity without revealing himself.

He could hire someone or he could find a friend that would be his representative on doing so. So, I guess that this Magic Mouse that you were saying is not true at all, because it is hard to find a proof that could prove that Satoshi was the one who announced this topic that you have posted.
