This is my personal thinking .. Satoshi Nakamoto is an individual, if it's a group or team I do not think it would be easy to have the same thought to get out of bitcoin when bitcoin gets more and more its value.
Satoshi nakamoto is the one who made or who found bitcoin, and satoshi nakamoto is found bitcoin on the year of 2009 and he is the genius who made the first crypto currency and right now the best crypto currency
