I never heard of this website and until now, you are the first one I hear saying that this site belongs to Satoshi. It's not though, It wouldn't make sense to ask donations in DASH:
https://www.cryptofight.com/donate/ If you are the creator of bitcoin, does it? not to mention that he is rich enough to not take any donations.
I read it in chats, then why donation button still on bitcointalk? Maybe he created Dash? Anyway i am not sure that's why i am questioning.
